Distribution and Abundance: Common.

Primary Habitat: General occurrence.

Flight Period: Single brooded in April and May.

Observations: The moth is under recorded. Although the female is occasionally taken at light and the male sometimes seen in rapid afternoon flight, most records have been by assembling. This means of attracting the males can be particularly successful early in the flight period. My own field records show seven males assembled in some thirty minutes at Grafton Park Wood on 23 April 1992. On the same day the males assembled so numerously in my garden in Kettering that they became the subject of attack by sparrows as they flew around the assembling cage.

L.O.N.: 1902. Earls Barton.

First Record: 1882, Hull & Tomalin.
