Some many which are specialized to existence in the nests staphylinids have been shown to feed occasionally of social insects, live in mushrooms. Many inhabit on slugs and snails, although apparently they are caves, underground burrows of vertebrate animals, not specialized to do so as are Cychrini (Coleoptera: and smaller soil cavities, even burrows that they (a Carabidae), nor have slugs and snails been shown to few of them) excavate.
