Status and Distribution
Formerly very local with records from the New Forest, Hants (1850), Worcestershire (1856-57), Sussex (1872 to c1900), West Suffolk (1889) and Surrey (c1900-39). Last recorded on 26th May 1939 in Durfold (which is believed to refer to Durfold Wood, Surrey - R J Heckford, pers. comm.) and is now considered Extinct.
It has been suggested that due to the retiring habits of this species it may still be present.
