Field Notes
Description:
The boldly striped black and white wing pattern is aposematic, warning off 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 so their coloration helps predators to warn them that they are not edible.
Adults roost in groups of up to 60 individuals on a nightly basis, returning to the same roost every night.
Caterpillars feed on various species of Passionflower, evading the plants' defensive trichomes by biting them off or laying silk mats over them.
Habitat:
Forests that can be found above 1000 m such as coffee crop lands. See this web site for distribution in Costa rica:
