Staphylinoidea

Silphidae is a subfamily of Staphlinidae beetles that are also known commonly as large carrion beetles, carrion beetles or burying beetles. There are two tribes: Silphini and Nicrophorini. Members of Nicrophorini are sometimes known as burying beetles or sexton beetles. The number of species is relatively small, at around two hundred. They are more diverse in the temperate region although a few tropical endemics are known. Both tribes feed on decaying organic matter such as dead animals. The tribes differ in which uses parental care and which types of carcasses they prefer. Silphini are consid

Ptiliidae (Ptenidium pusillum) is a family of very tiny beetles (including the smallest of all beetles) with a cosmopolitan distribution. They are colloquially called featherwing beetles, because the hindwings are narrow and feathery.

Hydraenidae is a family of very small aquatic beetles, sometimes called "Minute moss beetles", with a worldwide distribution. They are around 0.8 to 3.3 mm in length. The adults store air on the underside of the body as well as beneath the elytra which allows them to crawl underwater, often on the underside of the water surface tension, though they cannot swim. Some species have gills that effectively allow them to stay underwater indefinitely. Larvae vary from being fully terrestrial, to being aquatic at least in their earliest instars. The diet of hydraenid larvae and adults is thought

Agyrtidae, or primitive carrion beetles, are a small family of beetles belonging to Staphylinoidea. They are found in mostly temperate areas of the Northern Hemisphere and in New Zealand.

Jacobsoniidae are a family of tiny beetles belonging to Staphylinoidea. The larvae and adults live under bark, in plant litter, fungi, bat guano and rotten wood. There are around 28 described species in three genera:
