This Caterpillar hatches from a furry mass of eggs laid on a leaf of a foodplant. The Caterpillar is black and is covered with stiff dark brown hairs. It feeds on a wide variety of vegetative products, including :
and grows to a length of about 3 cms. When fully grown, the Caterpillar seeks a sheltered spot, where it forms the brown pupa in a sparse white cocoon.
The moth is rather wasp-like. Its wings are basically black, with yellow translucent spots on each wing. The moth has transverse black and yellow bands on its body. It has a wingspan of about 4 cms. The hind wings are only about half the span of the forewings.
The moths are rather laid back fliers, wafting more than flying around backyards. They are unusual for a moth species in that they fly in daylight hours, usually morning and evening.
Specimens have been taken in
When flying, the adult moths regularly emit ultrasonic clicks. The evidence suggests that this behaviour warns bats that the moth is distasteful and/or poisonous to eat, just as the bright black and orange wing pattern warns possible daytime predators of the same thing.
As generally in the genus Amata: the female has a fatter body than the male, but a smaller wingspan.
