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.
The Zebra Longwing or Zebra Heliconian is a species of butterfly belonging to the subfamily Heliconiinae of the Nymphalidae. It was declared the official butterfly for the state of Florida in the United States in 1996.
