Corticeus unicolor (Piller & Mitterpacher, 1783)
This is a rare beetle (RDB3), but which may be slowly increasing its UK range. However, Corticeus unicolor is still largely confined to the Sherwood Forest area of Nottinghamshire, but there are recent records from elsewhere in Nottinghamshire and from other counties. At Sherwood, this beetle has proved to be common, where it occurs underneath young Bracket Fungi growing on Birch and is best searched for by torchlight at night. A very surprising record away from Sherwood Forest, came in early March 2010, when we found an adult under the bark of a long dead Elm at Hare Hill Wood near Kersall and we have since recorded it at nearby Lound Wood, Eakring and there is also a recent record from the Trent Valley (A.Dutton).
