Subfamilies

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdomens exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of beetles. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.

One well-known species is the devil's coach horse beetle. For some other species, see list of British rove beetles.

As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to 35 mm (1.4 in), with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid in shape. Colors range from yellow and red to reddish-brown to brown to black to iridescent blue and green. The antennae usually have 11 segments and are , with moderate clubbing in some genera. The abdomen may be very long and flexible, and some rove beetles superficially resemble earwigs.

Some members of Paederina (specifically the genus Paederus), a subtribe of Paederinae, contain a potent vesicant in their haemolymph which can produce a skin irritation called dermatitis linearis. which in English has unfortunately acquired the inaccurate name Paederus dermatitis. The irritant pederin is highly toxic, more potent than cobra venom.
