Utetheisa

Utetheisa is a genus of tiger moths in the Erebidae family.

Caterpillars of many Utetheisa species feed on Crotalaria (rattlebox), and hence the genus as a whole is often called rattlebox moths. The adults usually have bright aposematic coloration and contain toxic pyrrolizidine alkaloids, which are used as a chemical defense and are also incorporated into the sex pheromones of the males.
