The Comet moth indigenous to Madagascar’s rainforests was described in 1847 by French entomologist Félix Édouard Guérin-Méneville. Though reared in captivity, their numbers remain endangered in the wild because of habitat loss.

The pupa remains enclosed in a large grayish-white cocoon closely resembling a sac. Because of its rainforest habitat, the pupa could be at the risk of drowning but is saved as the cocoon has many holes in it through which the rainwater seeps out and does not accumulate within. 

Adult Moth

Sexual Dimorphism: Present

Color and Appearance: When opened, the wings are bright yellow with about four reddish-brown eyespots, two on top and two below. The borders are also outlined in brown, while the topmost part of both sides has two brownish lines running parallel. When closed, the pattern is the same, with two of the four eyespots visible.

The wings are more rounded in females than males. There is a difference in their antennae too, as the males have long, feathery ones, while in females, it is as thin as a thread.
