Giant Silkworm Moth

Attacus sp.

Description:

This Giant Silkworm Moth is very colourful and has transparent triangular windows on both front and rear wings. I spotted it at 8:00 a.m. hanging on its cocoon, being buffeted by the morning breeze. It was in perfect condition and had clearly just eclosed. It remained in the same position all day and I was able to go back and take pictures at intervals until darkness fell in the evening.

Habitat:

This specimen had constructed its cocoon by sticking some leaves together (with silken threads) on a Kalamansi (Citrus microcarpa) in my back garden. I had noticed this several days before and mistakenly thought that it was the beginnings of a nest of Weaver Ants (Oecophylla smaragdina). I had disregarded it as these ants are very common here I had already taken many pictures of their nests.

Notes:

According to Wikipedia, the females of some species of Saturniidae (Giant Silkworm Moths) will remain on their cocoons, emitting pheromones to attract males, until they have mated before taking off in flight. So I am assuming that this one is a female. I think this specimen is Attacus lorquinii C. & R. Felder, 1861 (Saturniidae; Saturniinae; Attacini), but since I am not quite certain, I have opted for a safer "Attacus sp."
