Philippine Atlas Moth Attacus atlas cocoons

Giant Atlas Moth Attacus atlas, from the Philippines

Pairing is achieved in a cage that is ample for the size of the moths but not so large that they can become too separated. Larvae feed on Privet and are easily reared in conditions that are warm and moist. Atlas larvae will also feed on Tree of Heaven Ailanthus, Osier Willow Salix viminalis, Citrus and undoubtedly a number of other substitute plants outside their normal habitat.

To get moths to emerge, raise the temperature to 15 degrees C, and gradually up to 30 degrees C or more, and very humid. They need very warm and humid tropical conditions. At higher temperatures, soak the cocoons at least once or twice daily. The cocoons must drain and not be left lying in water.
