Agonum bicolor

Description

Agonum bicolor is a species of ground beetle in the Platyninae subfamily. It was described by Dejean in 1828 and is found in Japan, Kazakhstan, Mongolia and Russia. Besides those countries it can be found in the US state of Alaska, and British Columbia, Canada, where it was discovered in March 1981, on Bougie Creek. One of such species was found near Liard River in May 1981. 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.
