Distribution and Abundance:  Local.

Primary Habitat:  Grassland.

Flight Period:  Single brooded in July and August.

Localities:  Old Pastures, Newton Field Centre, Castor Hanglands and Barnack Hills and Holes. 

Observations:  The moth always seems to have been somewhat local in the county and appears to have become even more so in recent years. In the early 1960’s it was described as very common at Castor Hanglands but is certainly not so nowadays. Currently the only area that it appears to be at all common is on the acid soils to the west of Northampton where it was quite plentiful to light on 28 August 1997 at Brampton Golf Course alongside Harlestone Heath.

L.O.N.:  1907. Several localities. Common.

First Record:  1882, Hull & Tomalin.
