Empyreuma
spotted oleander caterpillar moth
Empyreuma is a genus of tiger moths in the family Erebidae, containing three species. The genus name derives from the Greek ἐμπύρευμα, meaning "a live coal covered with ashes." Adults exhibit striking aposematic coloration with orange and black patterns that mimic stinging wasps. Larvae feed exclusively on oleander (Nerium oleander), a toxic plant containing cardiac glycosides that the caterpillars sequester for their own defense. The genus is notable for its acoustic courtship behavior, with males producing sounds detected by female tympanic organs.
