The moths in this post are from cocoons imported from Sumatra (Indonesia). You may have seen them sold before on Actias, Insectnet and Facebook as Antheraea frithi. But, as you probably know, frithi does not occur on Sumatra. I'm almost certain that this is Antheraea sumatrana, a species restricted to Sumatra and closely related to Antheraea gschwandneri. Almost certain ... There are a few other candidates in the area. For now however and until someone proves me wrong, I will threat them as sumatrana. This is a colorful species, especially the males which often are bright orange. The larger females come in several color forms from yellow to brown. The wingspan of this species is between eleven and thirteen centimeter. Even with a good air movement, the males seem to have some difficulties in locating the females. Pairing is easier achieved in a small cage in a warm room.
