"Adults are known to frequent buildings for animal and human habitation in search of food, shelter, and for oviposition. The flies are commonly found in the presence of tainted food or decomposing organic matter. Larvae have been bred from blemished or partly decayed fruits and vegetables, various fungi, animal dung, human excreta, carrion, nests of starlings, sparrows, swallows, and from dead snails and earthworms. They have been recorded as parasites or predators on a wide variety of insects in the immature stages, belonging to the orders Lepidoptera, Hymenoptera, Orthopera, Diptera, and Coleoptera."(1)
