After a couple of weeks development, the chrysalids of the Northern (Cairns) Birdwing, Ornithoptera priamus (Linnaeus), have finally emerged. Two males were the result of the three that were observed. The third one was not found and may have been taken by a predator.
A spectacular butterfly to have in one's garden.
