Zebra Longwings

The caterpillar feeds on Yellow Passionflower (Passiflora lutea), Corky-stemmed Passionflower (Passiflora suberosa), and Two-flower Passionflower (Passiflora biflora). The adults are unusual among butterflies in that they eat pollen as well as sip nectar. This ability contributes to their longevity—3 months as an adult.[3] Because of their relatively long lifespan and their activity throughout the day, this is a popular species with butterfly houses. Another unusual feature is that adults roost in groups of up to 70, and return to the same roost each evening.
