The Pirate, Catacroptera cloanthe, is a distinctive butterfly belonging to the Nymphalidae family (Brush-footed Butterflies) and the subfamily Nymphalinae (Admirals, Pansies, Commodores, Diadems, Mothers–of-Pearl, etc.). Although it bears a superficial resemblance to the Commodores (genus Precis, tribe Junoniini), it is uniquely the sole South African representative of the tribe Kallimini. The genus Catacroptera is classified as ‘monotypic’, indicating that it contains only one species. The Kallimini tribe comprises 18 species in total, including the notable Oakleaf butterflies of Southeast Asia (genus Kallima).

Its primary habitats are grassy savanna and grassland, with occurrences at various altitudes across the continent. They show a preference for stream sides and seeps, as well as hilltops and ridges. The nominate subspecies Catacroptera cloanthe cloanthe is found on the eastern side of Africa. In the Western Cape, it can be found near sea level around Mossel Bay and Knysna. At higher latitudes, it is located at higher elevations. Within the grassland and savanna biomes of South Africa, it is found up to 1600 meters around Gauteng. In Tanzania, it ranges from 300 meters to 2200 meters, and in Kenya, as high as 2500 meters. Specimens are typically observed either singly or in small groups within grassy areas. They are highly cautious and easily startled, often flying 20-50 meters before settling again. The patient photographer will find that if they avoid sudden movements, and give the butterflies time to get used to their presence, habituation is possible and good images will follow.

Males frequently perch on small prominences or tall herbs to survey their territories and may also settle on bare ground or rocks. Females tend to be located near their host plants. Both sexes exhibit a preference for flower nectar, particularly from Blue Haze flowers (Tetraselago species), and are known to be attracted by fermenting fruit baits.

The West African subspecies Catacroptera cloanthe ligata is smaller, darker, and inhabits grassland and savanna from The Gambia to Nigeria and Cameroon.

The fiery orange coloration of the upper side of these butterflies is complemented by a shifting purplish-blue lustre that is perceptible only from certain angles. Conversely, the underside exhibits a more subdued pattern in brown and cream tones. Individuals seen during winter (dry season form) display darker undersides and upper sides compared to those observed in summer (wet season form).

In South Africa, their primary flight period extends from August to April. These butterflies have a relatively long adult lifespan, with the same individuals occupying territories for two to three months, showing signs of wear over time. Females are typically larger and paler in colour compared to males.
