Narrow Green-banded Swallowtail

EASY GARDEN BUTTERFLIES

Narrow Green-banded SwallowtailPapilio nireus lyaeus

Swallowtails are the largest and most charismatic of all butterflies. They are members of the family Papilionidae (Swallowtails and Swordtails). They received this name because those found in Europe possess elongated, swallow-like tails on their hindwings. We now know that not all ‘Swallowtails’ have these tails. 

The Narrow Green-banded Swallowtail Papilio nireus lyaeus has expanded lobes at the tailward corner of the hindwings instead of actual tails. It looks entirely black in flight, but the coloured bands show up well as it flutters its wings. It’s slightly smaller than the Citrus Swallowtail with a wingspan of 75-95mm. Males are slightly smaller than females and are more brightly coloured with brilliant turquoise-blue bands on the wings. The females’ bands are closer to true green, and their ground colour is a less intense black.

Swallowtails seldom settle during the day, preferring to swoop and flutter around flowers and their host plants. When feeding they hover in front of a flower or on a mud puddle, using their legs and feet to steady themselves.

Distribution

Narrow Green-banded Swallowtail is less widespread in South Africa than the Citrus Swallowtail. It’s found on the coastal side of the Great Escarpment from Swellendam in the Western Cape to the whole of KZN, Mpumalanga, Limpopo and Gauteng, also the north-eastern Free State.  It has followed ‘man-made forests’ in cities across the country and has recently moved onto cultivated Citrus as a host plant. 

Outside South Africa it’s found all over sub-Saharan Africa in forests and frost-free savanna.

Egg

Swallowtail eggs are generally similar across the family Papilionidae: tiny pearl-like spheres with flattened bases. They are white when laid, changing colour to pale yellow if fertile and then becoming green with faint brown mottling. Narrow Green-banded Swallowtail eggs are 0.95mm high by 1.15mm diameter.

They are laid on the young shoots and leaves of the host plant, held in place by an adhesive secreted by the mother. The egg stage lasts about five days.

Young caterpillar

Papilio nireus lyaeus

Young Narrow Green-banded Swallowtail caterpillars, like other Swallowtails, resemble bird droppings. When freshly hatched from the egg they are about 3mm long. They are more slender than Citrus Swallowtail larvae with more green colouration.

This camouflage gives them protection against predators like birds, which would not recognise them as a source of nutrition.

They have two rows of short spines along the body with forward-pointing ones behind the head. The tail is forked and also carries short spines. The thorax has longer spines than the rest of the body.

The caterpillars take about 24-30 days to reach full size, undergoing four moults.

Mature caterpillar

Fully-grown Narrow Green-banded Swallowtail caterpillars are green with pale grey underparts and yellow lines, and the thorax is blue-green.

If disturbed, all stages of this caterpillar will rear up and extrude a forked orange organ called an osmeterium. This emits a strong scent of oils from the host plant. Together with the eyespots on the thorax of a mature larva gives the impression of a small snake, which can startle away small predators.  

The final instar caterpillar takes about a week to ten days to reach a size of 35-45mm.

Pupa/Chrysalis

Narrow Green-banded Swallowtail pupa

Narrow Green-banded Swallowtail

Papilio nireus lyaeus

Narrow Green-banded Swallowtail pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. They hang from the girdle as shown here. They are wider than those of the Citrus Swallowtail with fewer projections and a smoother surface.

They are variable in colour from leaf green to pale brown depending on the surface they are formed on. 

The pupa is about 28-30mm long. The pupal stage lasts from two weeks to several months when the insect undergoes diapause as a pupa.

Host plants

Narrow Green-banded Swallowtail caterpillars feed on Rutaceae only; plants like White Ironwood Vepris lanceolata, Small Knobwood Zanthoxylum capense, Cape Chestnut Calodendrum capense,  Slender Cherry-orange Teclea natalensis, and Horsewood Clausena anisata. These are all excellent garden trees and well worth planting.

How to attract them

Gardeners can promote the presence of this butterfly by cultivating its preferred wild host plants. Other Swallowtail species, if present, will lay eggs on them and breed in the garden.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar. Leadwort Plumbago auriculata is a good nectar plant for Swallowtails, which are fond of large pink or red flowers like Coral Senecio, Hibiscus or Cape-honeysuckle. The males also like to suck mineral-laden water from water seeps and river banks. Sprinkling a little bone meal on wet sand may attract this and other butterflies.

Citrus Swallowtail

EASY GARDEN BUTTERFLIES

Citrus SwallowtailPapilio demodocus demodocus

The Citrus Swallowtail is one of the Papilionidae (Swallowtails and Swordtails). Although it’s called a ‘Swallowtail’ its hindwings lack the long tails that its relatives have.

Citrus Swallowtail is a large and conspicuous butterfly with a powerful flight and the restless nature typical of Swallowtails. Males (wingspan 100-120mm) patrol large territories looking for females and food sources. They are often found congregating on wet sand and mud around water sources.

Females (wingspan 110-130mm) are found on flowers and close to their host plants. The sexes are similar; females have an orange tint to the cream ring around a large eyespot at the upper corner of the hindwing (not visible here). 

Citrus Swallowtail is active from spring to autumn but it often peaks in midsummer. This is the reason for its other name, Christmas Butterfly. 

Distribution

Citrus Swallowtail occurs throughout South Africa and is common almost everywhere except remote arid areas with little human habitation. Because it uses the popular cultivated Citrus as a caterpillar host plant it is found in areas where its wild host plants are absent.

Outside South Africa it’s found all over sub-Saharan Africa, the moister parts of the Arabian peninsula, Madagascar and the Indian Ocean islands.

Not all Citrus Swallowtail caterpillars feed on the Citrus family of plants. Some, like this one, use Apiaceae (Umbellifers) and their colouring affords them camouflage when feeding on these plants.

The final instar caterpillar takes about a week to ten days to reach a size of 35-45mm.

Pupa/Chrysalis

Citrus Swallowtail pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. They hang from the girdle as shown here.

They are variable in colour from bark-like grey to leaf green depending on the surface they are formed on. Many have patches of green and grey.

The pupa is about 35-38mm long. The pupal stage lasts from two weeks to several months when the insect undergoes diapause as a pupa.

Host plants

Citrus Swallowtail caterpillars feed on plants in the Rutaceae (Rue and Citrus) family, which often grow in gardens. They also use Apiaceae (Umbellifers) like Fennel Foeniculum vulgare. Wild South African Apiaceae like Deverra or Peucedanum species are skin irritants and don’t make good garden subjects. There are many local Rutaceae that this butterfly uses in the wild. Examples are White-ironwood, Vepris lanceolata, Horsewood Clausena anisata, Small knobwood Zanthoxylum capense, and Cape-chestnut, Calodendrum capense.

How to attract them

Gardeners can promote the presence of this butterfly by simply growing a Lemon tree! Some people don’t like the way the caterpillars eat holes in the leaves, although they seldom arrive in sufficient numbers to do real damage. One way to divert their attention from the Lemon tree is by cultivating its preferred wild host plants. An advantage of doing this is that other Swallowtail species, if present, will lay eggs on them and breed in the garden.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar. Swallowtails are particularly fond of large pink or red flowers like Hibiscus or Cape-honeysuckle.

Meadow White

EASY GARDEN BUTTERFLIES

Meadow White Pontia helice

The Meadow White is one of the Pieridae (Whites, Tips and Yellows) subfamily Pierinae (Whites and Tips).

Meadow White is a small to medium-sized butterfly with a wingspan of 35-45mm. Its markings resemble the common migratory Pioneer Caper White Belenois aurota, but it flies more slowly and lower down. It settles often and is fond of flower nectar. It’s a pretty little insect with its underside marked in shades of green and yellow. The sexes are similar, with the female having black marks at the inner margin of the forewing and along the outer margin of the hindwings where the males are plain white.

Meadow White is often one of the first butterflies to emerge in spring. 

Distribution

Meadow White occurs throughout South Africa, particularly in grasslands. It typically does not frequent forests but it can be found almost everywhere apart from the hottest and most humid places. It’s also found in Namibia, Angola, Botswana, Zimbabwe and Mozambique. In East Africa it’s replaced by the Northern Meadow White, Pontia johnstonii.

Egg

Pontia helice

Meadow White eggs are typical of the family Pieridae: bottle-shaped, tapered at the top, with vertical ribs connected by horizontal cross-ribs. They are pale yellow, changing colour to dull orange if fertile. They are 1mm high by 0.5mm diameter, with 12-13 vertical ribs and 30-35 cross-ribs.

They are laid on the flowers, ovaries, and pods of the host plant. The egg stage lasts about five to nine days.

Caterpillar

Fully-grown Meadow White caterpillars are yellow with green underparts and stripes of green and bluish-grey. 

They have rows of black dots and those at the front of each segment are outlined with orange. 

They grow from 1mm to about 20mm in two to four weeks depending on conditions; there are usually four moults.

 

Pupa/Chrysalis

Pontia helice

Meadow White

Pontia helice

Meadow White pupae are attached to leaves or stems of the plant by a tail hook and a silken girdle spun over their ‘waist’. This holds them tight to the surface; they don’t hang down from the tail like Nymphalidae or from the girdle as do Swallowtail pupae and some other Pieridae.

They are variable in colour, some being greyish-green with yellow stripes, or pale purple or grey-brown with yellow stripes.

The pupa is about 18mm long. The pupal stage lasts from four days to two weeks depending on climate conditions.

Host plants

Meadow White caterpillars feed on plants in the Brassicaceae family, which often grow in gardens. Indian Mustard Brassica juncea, Garden Alyssum Alyssum minutum, and Cultivated Rocket Eruca sativa are popular host plants. In the wild they occur on Virginia Peppercress Lepidium virginicum and its relatives. It also uses Hedge-mustard Sisymbrium officinale and Yellow Mignonette Reseda lutea.

Meadow White is the only member of the African Pieridae that it’s easy to get onto garden plants. To market gardeners who grow Indian Mustard and Rocket commercially it’s seen as a ‘pest’ but the caterpillars are solitary. They are far less destructive than the invasive Cabbage White Pieris brassicae to which this butterfly is related.

Like most butterflies they welcome open sunny areas with lots of flowers to visit for nectar.

Common Mother-of-Pearl

EASY GARDEN BUTTERFLIES

Common Mother-of-Pearl Protogoniomorpha parhassus

The Common Mother-of-Pearl  is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

It’s one of the biggest and flashiest butterflies found in South Africa. Its wingspan varies from 65 to 90mm. Winter forms are darker and smaller than summer forms, with more extravagantly hooked forewing tips and hindwing tails. The basic pattern of markings remains the same.

They are related to the Commodores and Diadems, and like them, tend to skulk in shady places, particularly among plants with large leaves. They venture out into the open when the sun is shining. Males perch on the upper leaves of large plants and trees with wings at 90 degrees. Occasionally one will set off and patrol his territory. This usually tempts others out of their lurking places and a graceful dance follows, the iridescent uppersides flashing green, gold, and violet in the sun. This is one of the finest sights one can see in a forest garden,

Females stay close to the host plants and lay eggs on them. Both sexes are attracted to flowers. Males are not as strongly drawn to wet mud as are the other butterflies in this group.

Distribution

Common Mother-of-Pearl occurs along the coastal littoral and lowveld from East London to northern Limpopo along the escarpment.

Although it has a limited range compared to other butterflies covered in this series, it’s such a special butterfly and worth looking out for if you live along the east coast or in the lowveld. It’s easy to attract to gardens near natural forests and its host plants are simple to cultivate.

In Africa to the north, it occurs in most forested areas south of the Sahara Desert.

Egg

Protogoniomorpha parhassus

The Common Mother-of-Pearl is closely related to the Commodores and Diadems and has similar, but larger, eggs. They are green, barrel-shaped, and tapered towards the top with 16 white vertical ribs that don’t reach the apex, with faint cross-ribbing. They are laid singly on young shoots of the host plant, They are about 1.1mm diameter by 1mm high. The egg stage lasts about five days.

Caterpillar

Fully-grown Common Mother-of-Pearl caterpillars are black with bands of salmon-pink on the back between the bands of spines. The head has two long, curved, spiny horns. The body has seven rows of branched spines, one per segment. These are a translucent dull yellow with a dark metallic blue base. As the larva matures the salmon-pink changes to dirty brown. Although spiny they don’t sting or make you itch. They grow from 3mm to 50-56mm long over six weeks. There are normally four moults but some individuals have five. The caterpillars hide in the shade and are almost impossible to find.

Pupa/Chrysalis

Protogoniomorpha parhassus pupa

Common Mother-of-Pearl

Protogoniomorpha parhassus

Common Mother-of-Pearl pupae are similar in shape to those of Diadems and Commodores, with short spines on the back, but the edges and spines are more pronounced and the shape more angular. The colour and markings are very reminiscent of a curled up dead leaf, which helps camouflage it because it is usually formed in the leaf debris below the plants.

The pupa is about 30mm long. The pupal stage lasts from two to three weeks depending on climate conditions.

Host plants

Common Mother-of-Pearl caterpillar host plants are in the family Acanthaceae. They have been recorded feeding on Justicia and Isoglossa species. However the main host plants in South Africa appear to be African Coromandel Asystasia intrusa in the north, and Himalayan Ruellia, Phaulopsis imbricata, elsewhere. Both grow easily from cuttings and spread well.

How to attract them

Gardeners can promote the presence of this butterfly by cultivating its preferred host plants. African Coromandel is common in coastal and lowveld gardens, but Himalayan Ruellia isn’t usually offered for sale by nurseries. It’s worth cultivating someone who has a forest garden because it takes root easily from stem cuttings.

Common Mother-of-Pearl, unlike its relatives, is a shade lover. In winter it often enters houses, and hides behind the curtains, or sneaks into tool sheds. It helps to plant shrubs and trees with large leaves for them to hide in. If your garden has a sunny arena surrounded by plenty of cover, on sunny days they will emerge and delight you with their antics.

Garden Commodore

EASY GARDEN BUTTERFLIES

Garden CommodorePrecis archesia archesia

The Garden Commodore (aka Garden Inspector) is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

As its name suggests, this is a butterfly found often in gardens. Commodores are related to Pansies and have similar behaviour and habits, but there are some significant differences like their choice of caterpillar host plant.

Another difference is that whilst Pansies vary slightly in appearance with the seasons a winter form Commodore looks very different to a summer form one. Summer form Garden Inspectors are brown with conspicuous cream to buff-orange bands. Winter (dry season) forms are also brown, but have bands of maroon-red rather than buff to orange, and blue spots and bands on their forewing tips and outer edges. Their wingspan is 45-55mm. 

They are sun loving butterflies, but the two forms behave differently. Summer forms are found in open country where they frequent hilltops and bright sunny places. Winter forms tend to hide up in shady places and only come out on sunny days. The males are aggressively territorial and will choose a high point and chase away all other butterflies from it.

Distribution

Garden Commodores occur on the eastern side of South Africa, in grassland and savanna from Plettenberg Bay to Swaziland. Gauteng, Mpumalanga and Limpopo as well as the eastern side of North-West Province.

The species is found across Africa south of the equator in suitable habitats.

Egg

Fully-grown Garden Commodore caterpillars are entirely dark brown to black. The head has two short spiny horns. The body has seven rows of branched, black spines, one per segment. These are shorter than the spines on a Gaudy Commodore caterpillar. Although spiny they don’t sting or make you itch. They grow from 1.5mm to 42-46mm long over a month. There are normally four moults but when growth is slow there can be five. 

Pupa/Chrysalis

Garden Commodore pupae are similar in shape to those of Diadems and Pansies, with short spines on the back. The colour varies from dark brown to black, with a band of silver across the wing cases and abdomen.

The pupa is about 25mm long. The pupal stage lasts from two to four weeks depending on climate conditions.

Host plants

Garden Commodore host plants are in the family Lamiaceae: Sages, Mints and cultivated Coleus, in the genera Plectranthus and Coleus.

Favoured plants are Blue Boys Coleus livingstonei, Spike Spurflower Coleus subspicatus, Lobster bush Coleus neochilus, and Tall Spurflower Plectranthus ecklonii.

Like its close relatives the Pansies and Diadems it’s a sun-loving insect that’s often found on flowers. Males like to patrol hilltops and other prominent landforms.

Commodores and their relatives seek out sheltered places in winter to hibernate as adults. They often enter houses and hide behind the curtains, or sneak into tool sheds.

Southern Gaudy Commodore

EASY GARDEN BUTTERFLIES

Southern Gaudy CommodorePrecis octavia sesamus

The Southern Gaudy Commodore is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

Southern Gaudy Commodore is well-named because it’s one of the most brilliantly coloured medium-sized butterflies we have in South Africa. It’s the largest of our Commodores with a wingspan of 50-65mm. It’s also a superb example of seasonal dimorphism.

A winter form Gaudy Commodore looks very different to a summer form one. Summer form Gaudy Commodores are brilliant pinkish red to orange. Winter (dry season) forms were once thought to be a completely different butterfly species. They are deep iridescent blue that shifts in hue depending on the angle of view. This is set off by a band of red spots on the outer edge of each wing. The underside of this form is almost black.

As with the related Garden Inspector the two forms behave differently. Summer forms are found in open country where they frequent hilltops and bright sunny places. Winter forms tend to hole up in shady places like riverbanks and culverts and only come out on sunny days. The males are aggressively territorial and will choose a high point and chase away all other butterflies from it.

‘.

Distribution

Southern Gaudy Commodores occur along the coastal littoral and lowveld from East London to northern Limpopo as well as in the Drakensberg and other mountains and their foothills. They’re common in grassland habitats that have sufficient rainfall to support their host plants and rocky areas to provide shelter. They can withstand cold conditions because of their habit of hibernating in dark, sheltered places.

Southern Gaudy Commodores are found in Africa south of the equator. Its northern cousin Precis octavia octavia (which it resembles closely) occurs across Africa south of the Sahara to the equator.

Egg

The undersides of butterflies can look very different to their upper sides, so it helps to be able to recognise them. Also, Gaudy Commodores have a ‘change of the guard’ in spring and late summer. Occasionally (and very rarely) you might see one that is in between the summer and winter forms. This is the rare form transiens. They vary a lot. Some look like winter forms with a splash of summer form colour along the edge of the wings. Others are more of a mixture, with shades of pink or purple.

Common Diadem

EASY GARDEN BUTTERFLIES

Common DiademHypolimnas misippus

The Common Diadem is one of the Nymphalidae (Brush-footed Butterflies), subfamily Nymphalinae (Admirals, Pansies etc.).

The male Common Diadem is an amazing sight. His upper side is jet black with a large white blotch in the middle of each wing. Each blotch is ringed with a shifting iridescent blue lustre which is only visible from certain angles. His underside is attractive as well. 

This butterfly is an example of what we call sexual dimorphism, in which females and males look totally different. The female Common Diadem looks like an African Plain Tiger, because she mimics that butterfly to gain protection against predators who have learned to avoid that bad-tasting butterfly. 

The Common Diadem’s wingspan is like that of an African Plain Tiger – 60-80 mm.

A Common Diadem has a more nervous and active flight than an African Plain Tiger, and when it lands it will constantly move its wings up and down. We call this ‘pumping’.

Distribution

The Common Diadem is found across the eastern side of South Africa, avoiding the arid Nama Karoo and Succulent Karoo areas. It’s found in the fynbos areas of the Western Cape and has spread across the world, being found across Asia and the Americas where it’s known as the Danaid Eggfly.

It’s widespread in Africa and it’s found on the southern end of the Arabian peninsula as well as Madagascar and the Indian Ocean islands.

The body has seven rows of short, branched, black spines, one per segment. Although spiny they don’t sting or make you itch. They grow from 2mm to 48-50mm long over a month. There are normally four moults but when growth is slow there can be five. 

Pupa/Chrysalis

Hypolimnas misippus

Common Diadem pupa

Hypolimnas misippus

The Common Diadem pupa is variable in colour, from sandy to black through various shades of brown. It closely resembles that of a Pansy or Commodore, having the rounded shape with spiny back typical of Nymphalinae pupae. It’s usually formed concealed on the host plant or in leaf debris where it is well camouflaged. Like all Nymphalidae pupae it is attached to its substrate by its tail. The pupa is 22-25mm long and the adult usually emerges after 4-6 weeks.

Host plants

Like many widespread butterflies, Common Diadem has a wide host plant range. In South Africa its main host plant is African Coromandel Asystasia intrusa, but it also uses Justicias like Veld Justicia Justicia protracta, Moss-rose Purslane Portulaca grandiflora, and Ruellias like Veld Violet Ruellia cordata.

The Common Diadem female shown on the header is the ‘nominate’ form. She resembles the local subspecies orientis of the African Plain Tiger. Form inaria, shown here, is a mimic of the rarer Tawny Plain Tiger, Danaus chrysippus dorippus. Unlike that subspecies this form of Common Diadem is not rare.

Common Diadem females mimic several subspecies of the Plain Tiger. This one has the white hindwings reminiscent of  White-winged Plain Tiger Danaus chrysippus alcippus. The amount of white is variable, and forms exist that mimic Plain Tiger subspecies we never see in South Africa.

Pearl Charaxes

EASY GARDEN BUTTERFLIES

Pearl CharaxesCharaxes varanes varanes

The Pearl Charaxes or Pearl Emperor is one of the Nymphalidae (Brush-footed Butterflies), subfamily Charaxinae (Emperors, Queens etc.). It’s one of our most charismatic butterflies.

When seen flying against a backdrop of deep green vegetation their pearly white and orange wings  look almost luminous. It’s an unforgettable sight. By contrast their undersides look like dead leaves. The camouflage is highly effective.

The Charaxes are the swashbuckling ‘big flashies’ of the butterfly world. They aren’t typical garden butterflies because they tend not to visit flowers, preferring to inhabit the forest canopy. There they fly high, engaging in aerial battles with other big butterflies and even birds. They are usually regarded as being wild species that are scarce and difficult to observe.

Having said that though, there are a few species whose caterpillar host plants are often found in gardens. This is one of them. Its wingspan is from 60 to 90mm making it one of the biggest garden butterflies. 

Although it’s not a regular nectar feeder an adult Pearl Charaxes has been known to visit large flowers like Strelitzia. It is not difficult to observe them in a garden setting. The kind of fruit bait people use to attract fruit-eating birds works on these. They are not as strongly attracted to dung and carrion as other Charaxes species are.

Distribution

The Pearl Charaxes is found commonly on the eastern side of South Africa in coastal, montane, and riverine forests. Its range stretches from Mossel Bay to Limpopo. From the Eastern Cape northwards, it’s found from the coast to the mountains. In the Lowveld it can be seen anywhere close to a forest or thick woodland.

The species is found widely across tropical sub-Saharan Africa.

Egg

Charaxes varanes varanes

Charaxes lay their eggs singly, on the surface of leaves. They are  large and almost spherical with flattened tops carrying fine ribs radiating from the centre . When freshly laid they are pale yellow to green, developing a dark ring around the upper surface if fertile.

Pearl Charaxes eggs are 1.25mm high and 1.5mm in diameter. The egg stage lasts about nine days, then the young larva eats its way out and usually consumes the empty shell.

Caterpillar

Pearl Charaxes

Charaxes varanes varanes

Charaxes caterpillars have characteristic ‘head shields’ in the shape of a hand with the ‘fingers’ (known as ‘horns’) pointing back towards their body. They have roughly cylindrical bodies with no hair or spines, and a forked or ‘bifid’ tail. They usually have a characteristic marking on the middle of the back. The skin is finely rough with many tiny warts.

Young caterpillars’ head shields are usually dark and large in proportion to their bodies. As they grow the colour changes to match the (usually green) colour of the body. They eat leaves from the edges and spin a silken pad that they rest on between feeding sessions.

Fully grown Pearl Charaxes larvae are deep green with large, splayed head horns. They have two or three whitish bird-shaped marks on the back.

They grow from 4.5mm to about 52mm over four moults. The process usually takes about about five weeks but it can take a lot longer in winter when they enter diapause.

Pupa/Chrysalis

The Pearl Charaxes pupa is green and egg-shaped. Like all Nymphalidae pupae it is attached to its substrate by its tail. It is usually formed on the same silken pad the caterpillar used as a resting perch during its development.

The pupa is 25-28mm long and the adult usually emerges after 2-3 weeks. This may take longer in unfavourable conditions. Before emergence the pupal shell becomes transparent and the adult inside becomes visible.

Host plants

Pearl Charaxes caterpillar host plants are common trees and shrubs so if you plant them in the garden the butterfly will arrive by itself. They include Dune False-currant Allophylus natalensis, African False-currant A. africanus and Simple-leaved False-currant A. dregeanus. They also use Dune Currant Searsia laevigata and Spiny Currant S. longispina

How to attract them

Gardeners wishing to attract this butterfly would need to commit to planting a tree, but False-currants do not grow very large and prefer the understorey. They are attractive trees whose flowers’ nectar is very attractive to butterflies.

Nectar plants are not the best way to attract this butterfly. Deliberate baiting with fermenting fruit is the secret to success.

Southern White-barred Charaxes

EASY GARDEN BUTTERFLIES

Southern White-barred CharaxesCharaxes brutus natalensis

The White-barred Charaxes or White-barred Emperor is one of the Nymphalidae (Brush-footed Butterflies), subfamily Charaxinae (Emperors, Queens etc.). ‘Southern’ because this is the southern subspecies of an Africa-wide species. This male is perching atop a Strelitzia nicolai leaf, watching his territory for intruders.

The Charaxes are the swashbuckling ‘big flashies’ of the butterfly world. They aren’t typical garden butterflies because they tend not to visit flowers, preferring to inhabit the forest canopy. There they fly high, engaging in aerial battles with other big butterflies and even birds. They are usually regarded as being wild species that are scarce and difficult to observe.

Having said that though, there are a few species whose caterpillar host plants are often found in gardens. One of them is this one. Its wingspan is from 60 to 90mm making it one of the biggest garden butterflies. 

Although it’s not a regular nectar feeder an adult White-barred Charaxes has been known to visit large flowers like Strelitzia. It is not difficult to observe them in a garden setting. The kind of fruit bait people use to attract fruit-eating birds works on Charaxes. And if you have a dog, it will leave pieces of Charaxes bait all over your lawn… it will also come to your outside dining area to help itself to some wine!

Distribution

The Southern White-barred Charaxes is found across the eastern side of South Africa, traditionally only found in the moist subtropical areas. The species is found over a wide area of sub-Saharan Africa.

Recently its host plants have been planted well outside their historic range, often in attempts to replace exotic street trees with indigenous, although not necessarily locally indigenous, species. In addition it has shifted to using the foliage of a widely distributed exotic tree. 

As a result, this butterfly is now found in Cape Town, Bloemfontein, and Johannesburg!

And it is spreading…

The White-barred Charaxes pupa is green and has a squared-off abdomen. Like all Nymphalidae pupae it is attached to its substrate by its tail. It is usually formed on the same silken pad the caterpillar used as a resting perch during its development.

The pupa is 25-28mm long and the adult usually emerges after 2-3 weeks. This may take longer in unfavourable conditions. Before emergence the pupal shell becomes transparent and the adult inside becomes visible.

Host plants

Southern White-barred Charaxes caterpillars eat the leaves of trees like Natal Mahogany Trichilia emetica, Cape Ash Ekebergia capensis, and Honeysuckle-tree Turraea floribunda. They also use the exotic invader Syringa Melia azedarach. This is almost everywhere in SA at present. We’re not advocating you plant this to attract them, but it goes to show that it’s an ill wind that blows nobody any good!

How to attract them

Gardeners wishing to attract this butterfly would need to commit to planting a tree that can grow rather large. Having said that they are attractive trees with the ability to withstand a certain amount of cold and drought conditions.

Nectar plants are not the best way to attract this butterfly. Deliberate baiting with fermenting fruit is the secret to success.

African Grass Blue

EASY GARDEN BUTTERFLIES

African Grass BlueZizeeria knysna knysna

African Grass Blues are tiny (wingspan 18-24 mm), low-flying butterflies in the Lycaenidae (Gossamer-winged Butterflies), subfamily Polyommatinae (Blues, Bronzes, Hairstreaks etc.). Blues are tiny to small butterflies, many of which have brilliant blue uppersides (although some are dull grey or brown). 

The sexes differ slightly on their upper sides. Male African Grass Blues are shiny violet-blue above with a well-defined grey wing margin. They differ from their females which are charcoal grey with the bases of the wings being sky blue with ill-defined margins. The underside of both sexes has patterns of grey-brown spots and arrow-marks on a whitish grey ground.  

African Grass Blues fly very low and spend most of their time in the grass – hence their common name. They feed on low-growing flowers and like to sit on damp earth and mud, sucking up dissolved minerals. The sexes fly together and engage in courtship when they encounter one another.

 

Distribution

African Grass Blues are found all over South Africa except for the central Nama Karoo and the highest altitude grasslands. They are common all over Africa, Madagascar, and the Indian Ocean islands. The Asian Grass Blue subspecies Zizeeria knysna karsandra is found in North Africa, southern Europe, the Middle East and across tropical Asia to Australia.

Egg

Female African Grass Blues lay tiny, pale blue-green eggs singly on buds or flower stalks of the host plant. They turn white as they mature. They are flattened disks 0.5mm in diameter by 0.25mm high.  They have double rows of whorled white ribs that are joined by horizontal ribs on the side to create a pattern of triangles with a tiny mole where they meet. There is a prominent dark mark at the centre of the top. The egg stage lasts about five days.

Caterpillar

Zizeeria knysna knysna

African Grass Blue

Zizeeria knysna knysna

African Grass Blue caterpillars are tiny. They are slug-shaped, as are most caterpillars of the Lycaenidae. Fully-grown caterpillars vary in colour from pale green to dull mid-green, with pale whitish diagonal side markings and a pale stripe along the back. The skin is covered in tiny bristles and appears velvety. Young larvae eat slots into the leaves of the plant and conceal themselves in those. Older larvae wrap themselves around a leaf and consume it – they are very hard to see when they do this. They grow from 0.8mm to 10-11mm long in three moults over two to three weeks. They have a ‘honey gland’ on their rear segments like many other Lycaenidae, which attracts the attentions of ants. 

Pupa/Chrysalis

African Grass Blue pupae are covered with tiny bristles. They vary in colour from pale yellow-green to darker green with a varying amount of grey speckling. The caterpillars pupate in debris below their host plant. They are attached by tiny hooks on their tail to a silken pad spun by the larva and by a silken girdle around their ‘waist’. They are about 7-8mm long, and of a typical rounded Lycaenid shape. The adult normally emerges in about one to three weeks although it can be longer in cold or dry conditions.

Host plants

African Grass Blue caterpillars feed on a variety of plants from various families. One of the best-known is the Creeping woodsorrel, Oxalis corniculata – a common lawn weed found all over Africa. Few gardens will not have these little Blues flying around their lawn. Not all gardeners are fond of this plant and even fewer like one of its other host plants, Devil-thorn Tribulus terrestris!  It also uses plants in the Pea family, Fabaceae, like Lucerne, Medicago sativa

How to attract them

It’s very difficult to prevent this little species from appearing in a garden because a main host plant is a widespread lawn weed! This is one of the best arguments for avoiding weed killers and insecticides, accepting biodiversity into the lawn environment. Think of Creeping woodsorrel as an attractive ground cover with benefits!
