Distribution and Abundance: Fairly common.

Primary Habitat: Woodland.

Flight Period: Almost entirely single brooded from May to July.

Observations: The small second brood appears to be extremely infrequent in Northamptonshire, but does account for old records from Weekley Hall Wood on 23 August 1938 and 6 September 1923. The moth has been observed entering and exiting light traps without returning on a very regular basis. Where traps are left overnight this tendency may lead to some understatement of its true abundance.

L.O.N.: 1907. Many localities. Chiefly in woods. Common.

First Record: 1881, Porritt.
