Sadly, the female butterfly will also lay her eggs on other introduced PASSIFLORACEAE such as:
but the caterpillars cannot thrive on these plants.
The caterpillars are brown, with branched black spines arising from black spots all over the body. The caterpillars bunch together initially, but as they mature, separate onto different leaves. They grow to a length of about 3 cms.
The pupa is cream, with striking black markings, and rows of black outlined orange spots along the abdomen. It has two blunt horns on its head. It hangs head downward by a silk cremaster from the foodplant. It has a length of about 2 cms.
The forewings of the adult butterflies are transparent, with black spots.
The hindwings are white with a subterminal black arc, and a black border containing white spots. The mouthparts are unusual in being bright yellow. The butterflies have a wing span of about 6 cms. They are inclined to congregate around larval foodplants.
The eggs of this species are ellipsoidal, ribbed, and a creamy-yellow, and each has a height of about 1 mm. They are laid in clusters of several dozen on a leaf or stem of a foodplant.
The species is found in:
and in most of the north and east of Australia, including:
This is the only Glasswing found in Australia.
