I observed a Julia Heliconian depositing eggs on a nearly-defoliated Corky-stem passionflower, Passiflora suberosa. Fortunately, I had other plants available, and I was able to raise a caterpillar to adulthood. As this study was ongoing, I found additional caterpillars on a cultivated plant, Twoflower passionflower, Passiflora biflora. The caterpillars were easy to raise, and it was easy to see when a caterpillar had molted into a new instar. The adults, unfortunately, were not anxious to be photographed. While in the rearing cage they would not spread their wings; when released they flew off immediately without giving me a chance to get a picture!
