Description

The wingspan is 38–44 mm (1.5–1.7 in) for males and 40–45 mm (1.6–1.8 in) for females.[1] The male and female are very similar in colour. The upper surface of the wings is near black with large yellow patches on the forewing and hindwing. There is some reddish brown on the veins near the base of the forewings. The underside has patches of yellow corresponding to the upperside. The base of the undersurface of the wing has orange-brown markings with black spots. The margin of the wing on the undersurface has black lines on an orange-brown background.[2]

Distribution

It is found from the eastern subtropical forest areas of South Africa, through Swaziland, Zimbabwe,[2] and to Uganda, the Congo and Kenya.[3]

Life cycle

Larvae

The larvae feed on Triumfetta (including T. tomentosa), Hemannia, Hibiscus and Cephalomma species. When young, they group together on a mass of silk that they spin on the food plant, but as they grow older they venture out alone to different parts of the food plant.

Pupae

The pupae have a whitish to yellowish background with two rows of yellow and black markings down the back, but the pupa becomes dark coloured close to hatching. The wing areas have fine black veining on a whitish to yellowish background, but the black and yellow wings show through the shell of the pupa near hatching.

Adults

Adults are on wing year round but are more common in warmer months.[1] They have a slow, weak flight pattern and stay close to the ground, favouring sunny areas in forest clearings or on the edges of forest. The adults feed on nectar from flowers.[2]
