The adults mainly feed on fruit, using a barbed proboscis to drill into the juicy innards — but the males sometimes put these mouthparts to a use much more befitting of their common name. They’re known to pierce the skin of sleeping animals and drink blood, a form of “mud-puddling" behavior to obtain salts and other nutrients. These nutrients are then passed on to females during mating as a nuptial gift.
The male moths are capable of feeding from humans, but while the wounds they inflict are painful they’re not considered to pose any health risks.
