Agonum impressum

Description

Agonum impressum is a species of ground beetles in the subfamily Platyninae. Beetle length is from 8–9.5 millimetres (0.31–0.37 in). The upper part of the body is of copper, bronze, or green colour. Rarely, the species have two-tone colour. The elytron have five to seven very large, and bright gaps. The species live mostly near the water. It is found in several locations throughout Europe and Asia, including in the Mordovia region. Agonum is a large genus of ground beetles in the subfamily Harpalinae, tribe Platynini. They are mid-sized to smallish beetles, typically with dark metallic hues – often reddish or bronze, but sometimes black, green etc. The genus is generally native to the Holarctic and the Mediterranean region; their southern limit in Central Asia and the Himalaya region is less well understood, and they seem to range outward a bit out of their core regions (e.g. into East Africa). They are wet-loving throughout their life cycle; for example, the genus is well represented in Ireland, where they are more plentiful than anywhere else in Europe.
