Distribution and Abundance: Rare.

Primary Habitat: Woodland.

Flight Period: Single brooded in June and July.

Records: 22 June 2003 Pitsford Reservoir (P. Horsnail), 9 June 2005 Ring Haw (R. Follows), 3 July 1993 Longthorpe (W. Pugh) and 22 June Old Sulehay Forest (R. Follows).   

Observations: Formerly the species was known to occur at Bedford Purlieus where it was last seen in 1975. Although both of singletons the 2005 records from Ring Haw and Old Sulehay Forest appear to confirm that it is still present at low density in the county’s north eastern woodlands. The 2003 Pitsford record has not been repeated and is thought to be an immigrant as the site has been trapped nightly throughout the flight period since the record.

L.O.N.: 1903. Weedon.

First Record: 1843, Castor Hanglands, Whitewell.
