The julia butterfly is a yellow-orange tropical butterfly with long forewings. It is about 3-4 inches wide and is from the family Nymphalidae. The female julia is a duller shade of orange and has more dark markings. The small, yellow-to-gold eggs are oval and the pupa is angular. The julia caterpillar feeds on passion flower vine (Passiflora); the adult sips nectar from the flowers of the lantana and shepherd's needle. Julias are found from South and Central America to the southern USA. The julia belongs to the Heliconians, tropical butterflies that have a large head and have a bad taste and smell. It is a brush-footed butterfly.
