Members of the Amblyoponinae (especially Amblypone silvestrii) are called Dracula ants, after Count Dracula, the fictional vampire, referring to their unusual feeding habits; queens and workers practice a form of "non-destructive cannibalism", chewing holes into and feeding on the haemolymph (insect "blood") of the colony's own larvae.
Adetomyrma cassis is only known from a single male collected in the Ambatovaky Reserve, Madagascar.
