small carrion (dead insects, snails, smaller vertebrates) -- only few species are breeding in larger vertebrate carcases and feces; some are able to develop on decomposing vegetable matter (e.g., melon/tomato pulp); some groups prey on snail, earthworms, spider eggs, turtle eggs; several genera include specialized parasitoids of arthropods (various Orthoptera, tenebrionid beetles, cockroaches, mantids, cicadas, millipedes) or ant/termite nest dwellers(1)
