Issoria hanningtoni, the Hannington's fritillary, is a butterfly in the family Nymphalidae. It is found in Sudan, Kenya and Tanzania. The habitat consists of highland forests. Description The upperside of the wings is pale orange with strong blackish brown markings, the underside has silvery spots, common to many fritillaries. Ecology The caterpillars feed on Viola abyssinica. Habitat Hannington's fritillary can be found in montane forest above about 1,700 m. Behaviour Hannington's fritillary has a low down, fast and direct flight. It prefers open forest glades, where it is often not uncommon. The silver spots on the underside of the wings may be perceived by preditors as dew-drops on grass, mimicking the butterfly's favorite overnight resting place.
