Amerila

Amerila is a genus of moths in the subfamily Arctiinae. A number of species in this genus have a special defence mechanism when they are in their adult stage. When disturbed, they exude a frothy yellow fluid from glands beside the eyes, while making a sizzling noise to ward off their attacker. Similar behaviour has been observed in fertilised females of the North-American moth Utetheisa ornatrix.
