Yorkshire Status: Scarce and local resident.

Sutton & Beaumont, 1989: Previously only doubtfully recorded in Porritt's list (1883-86). This species suddenly appeared in 1980 and has undergone a spectacular range expansion since then, although it has been suggested it could also decline with equal rapidity! (PQW pers. comm.). It seems to be a common prey item for long-eared bats, several records below are of wings found below the roosts and S. & J. Warwick comment that wing remains suggest it is much more common than light trap catches would indicate. A.M. Riley also reports it to be regularly taken in Rothamsted Insect Survey suction traps but not often at light.

Beaumont, 2002: This moth has declined dramatically during the past decade and is now very infrequently reported.

Current status (CHF, 2011): In national decline. Recent Yorkshire records have been confined to the south-east and to the Teesside area.
