Agonum darlingtoni

Description

Agonum darlingtoni is a species of black coloured ground beetle from Platyninae subfamily, that can be found in the United States and Canada. 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.
