Waxworm
Waxworms are the caterpillar larvae of
wax moths, which belong to the snout moth family. Two closely related species are commercially bred – the lesser wax moth and the greater wax moth. They belong to the tribe Galleriini in the snout moth subfamily Galleriinae. Another species whose larvae share that name is the Indian meal moth, though this species is not available commercially. The adult moths are sometimes called "bee moths", but, particularly in apiculture, this can also refer to
Aphomia sociella, another Galleriinae moth which also produces waxworms, but is not commercially bred. Waxworms are medium-white caterpillars with black-tipped feet and small, black or brown heads. In the wild, they live as nest parasites in bee colonies and eat cocoons, pollen, and shed skins of bees, and chew through beeswax, thus the name. Beekeepers consider waxworms to be pests.
Galleria mellonella will not attack the bees directly, but feed on the wax used by the bees to build their honeycomb.
