Glasswing feeding on Easter Daisy
We have found the caterpillars on an exotic Passionfruit vine.
According to Roger Kitching in his book, The Butterflies of Australia, the males capture a newly hatched female, "carrying them to the ground where they mate forcibly. Mating lasts for 90-150 minutes and the male deposits a sphragis." A sphragis prevents other males from then mating with her.
The butterflies have a weak flight. We have sometimes come across them sitting on grass in the regeneration paddock roosting for the night.
