Distribution and Abundance: Local.

Primary Habitat: Woodland.

Flight Period: Single brooded from July to October.

Localities: Salcey Forest, Weldon Park, Brampton Wood and Harringworth Lake.

Observations: In my experience the moth is only seen in very small numbers at m.v. light in the county. The only time that I have seen it more plentifully was at actinic light in the 1970’s in Grafton Park Wood. My own field records show that it has become noticeably less common over the past two decades. Whereas I recorded it in small numbers in the county in most years during the 1990’s I have not seen it since. Pitsford Water light trap records for the past decade shows only one moth being taken on 21 September 2006. This constituted a reserve record.

L.O.N.: 1907. Near Kettering, Northampton, Geddington Chase. Not common.

First Record: 1882, Hull & Tomalin.
