A general term for insects belonging to the family Staphylinidae in the order Coleoptera. Approximately 30,000 species have been recorded worldwide, and approximately 900 species from Japan, but many new species are expected to be recorded in future research. The upper wings are usually extremely short, and the hind wings are folded finely underneath. The large, exposed abdomen can be freely bent upward. Most species are small, with a body length of 10 mm or less. Both adults and larvae wander around on the ground, preying on small animals such as insects, but many species are thought to be fungivorous.
