Zebra Heliconian , also called Zebra Longwings, they are common in south Florida and south Texas. It is a very rare stray in North Carolina however, which has been recorded from several North Carolina counties in the piedmont and coastal plain. 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.
