Acrotrichis is a genus of featherwing beetles, Ptiliidae. At least 24 species of the genus occur in Britain. They are broad, but not very convex, dark in colour and measure from 0.5 to 1.1 mm in length. The posterior pronotum partly overlaps the anterior part of the elytra.

Beetle is a general term for insects of the order Coleoptera. There are known to be over 370,000 species of beetle, outnumbering all the known species of vascular plants, and six species of beetle for every one vertebrate, with an estimated five million more species yet to be discovered.
Beetles undergo a complete metamorphosis, with a distinct pupal stage intervening between life as a larva and a sexually mature adult. As with other insects of this type, the larvae stage represents the principal feeding stage. Most adult beetles have a robust, hard external skeleton (carapace) which acts like body-armour and a pair of horny wing-cases (elytra), which usually completely cover the hind part of the body including the abdomen.
Beetles display a wide variety of life-styles and behaviour, indeed an interest in beetles inspired Charles Darwin to study evolution.

Bembidion is a genus of over 100 species of small (three to six millimetres in length) beetles of the ground beetle family, Carabidae. Most of the species live beside water, either stagnant or running, and most species hibernate. Colouration varies between species, Bembidion lampros which is common in Britain is a uniform bronze-black colour; Bembidion tricolour, common in the Alps, has a bicoloured elytra - the anterior half reddish yellow, the posterior metallic black or blue;
Bembidion genei has a metallic green coloured body and four yellow spots on the elytra.

Blapsidae are a family of nocturnal black beetles, whose wings are generally obsolete and their elytra soldered together. They are to be found in gloomy damp places and when seized discharge a peculiar smelling liquid in self- defence.

Blethisa is a genus of beetles of the family Carabidae. Blethisa multipunctata is a black beetle with a bronze sheen, between 10 and 13 mm long, with rather short antennae and rows of fine punctures and two rows of large dimples on its elytra. They live on swampy ground next to stagnant water, especially marshes in lowlands.
