Acrotrichis chevrolati is a beetle fromthe dwarf beetle family (Ptiliidae).
features
The beetles reach a body length of 0.5 to 0.55 millimeters, making them the smallest European species of the genus Acrotrichis . The body is black in color and has no metallic shimmer, the wings are very rarely dark brown in color. It lacks feeler bristles on the sides. The pronounced pronotum is sometimes denser on the sides, otherwise it is loosely structured in dots. The cover wings are almost equally wide over the entire length and only very slightly tapered at the rear. The pronotum is not or only slightly wider than the wing. Acrotrichis chevrolati is slightly smaller than the similar Acrotrichis montandoni . The antennae are dark with the first two basal sections reddish in color. They are longer than those of the otherwise similarly large Acrotrichis sericans . The legs are brown-yellow, the rails ( tibia ) are often clouded. The rails of the forelegs have only three apical bristles on the underside.
Occurrence and way of life
The species is found in northern and central Europe from southern England, Denmark, southern Scandinavia and Finland and Karelia to the south of France and Italy. In Central Europe, the species is only locally distributed and rare.
