Achroia grisella, the Lesser Wax Moth, is a small moth of the snout moth family (Pyralidae), wherein it belongs to the subfamily Galleriinae. It is the only unequivocally recognized species of genus Achroia. The Greater Wax Moth (Galleria mellonella) is a quite close relative; though placed in a distinct genus, it still belongs to the same tribe the Galleriini within the Galleriinae. Their caterpillars larvae are among the best-known "waxworms", as they are widely bred as food for pets such as lizards or fish.
