Distribution and Abundance: Fairly common.

Primary Habitat: Waste ground.

Flight Period: Single brooded in July and August.

Observations: The species was regarded as not common in a review of Castor Hanglands for the years 1911 to 1960 and there are no pre 1940 records for this site. With the advent of m.v. light trapping in the 1950’s records for the moth increased more accurately reflecting its true distribution within the county. The caterpillar was fairly common feeding on mugwort in the autumn of 2004 at Barford Meadows.

First Record: 1936, Cooper.
