Bembidion biguttatum
Several over-wintering pairs of this small Ground Beetle, were found underneath a large log at Eakring Meadows in mid-February 2009 and large numbers were found in April 2010, under detritus at the edge of a large area of water. Measuring around 5mm in length, this is an obviously overlooked species, but which is widespread across much of the UK. There are two other Bembidion species, which are extremely similar, but generally restricted to around coastal areas.
