Ophonus puncticeps
The Ophonus are a difficult group of seed eating ground beetles to identify and accurate ID is really only obtainable by microscopic examination of the male genitalia (see below) which is characteristic to species. Despite being ground beetles, the easiest way to find them, is by examining the curled up flowers of Wild Carrot, in which they often rest by day. Ophonus beetles all typically ahev a south-easterly UK distribution and there are several common species. Ophonus puncticeps is one of the commonest, with several of these being found at Warsop Main Pit Top in early September 2011, the first time we had actually looked for them.
