Heliconius charithonia
''Heliconius charithonia'', the zebra longwing or zebra heliconian, is a species of butterfly belonging to the subfamily Heliconiinae of the Nymphalidae.〔( Card for ''charithonia'' in LepIndex. Accessed 3 August 2007. )〕〔 The boldly striped black and white wing pattern is aposematic, warning off predators.
The species is distributed across South and Central America and as far north as southern Texas and peninsular Florida; there are migrations north into other American states in the warmer months.
Zebra longwing adults roost communally at night in groups of up to 60 adults for safety from predators. The adult butterflies are unusual in feeding on pollen as well as on nectar; the pollen enables them to synthesize cyanogenic glycosides that make their bodies toxic to potential predators. Caterpillars feed on various species of Passionflower, evading the plants' defensive trichomes by biting them off or laying silk mats over them.
==Description==
The caterpillars are white with black spots and have numerous black spikes along their body. Adult butterflies are monomorphic of medium size with long wings. On the dorsal side, the wings are black with narrow white and yellow stripes, with a similar pattern on the ventral side, but paler and with red spots. The wingspan ranges from 72 to 100 mm.〔(【引用サイトリンク】url=http://entnemdept.ufl.edu/creatures/bfly/zebra_longwing.htm )〕
