Distribution and Abundance:  Very local

Primary Habitat:  Woodland.

Flight Period:  Single brooded from May to July.

Localities: Hazelborough Wood, Pentmore Wood and Longmoor Spinney.

Observations: Always local, the species has contracted its range southwards and is now only known to occur in the Hazelborough Forest area in south Northants where it was found to be well established in 1991. In 2007 it was taken at light in Longmoor Spinney just to the south-west of Hazelborough Forest in SP63, confirming the belief that there are other undiscovered colonies in suitable woodland in the south of the county. All of the moths that I have seen are of the lighter form and are sometimes common at light in Hazelborough. It was last seen in Salcey Forest in 1969 and despite much recording the record has not been updated. Earlier localities with dates of last records include:-  Bedford Purlieus - pre 1960, Oundle - 1954, Newton - 1954  and Weekley Hall Wood -1919.

L.O.N.:  Castle Ashby.

First Record:  1841, in a wood near Sudboro’, Doubleday.
