Distribution and Abundance: Rather local.

Primary Habitat: Woodland.

Flight Period: Double brooded in May and again in August.

Localities: Salcey Forest, Brampton Wood, Glapthorn Cow Pasture and Easton Hornstocks.

Observations: Generally the species is encountered in small numbers in most woodlands, the most commonly that I have seen it is in Hazelborough Forest. Eighteen first brood moths were recorded there in May 2005 and nine second brood moths on 29 August 2009. Both broods of the moth have been recorded as singletons at Pitsford Water, one in 2006 and the other in 2009. On 1 April 1994 it was recorded at Hazelborough Forest, much earlier than its normal flight time.

L.O.N.: 1907. Many from Kettering, northwards. Common, but does not appear in Northampton lists.

First Record: 1842, Clark.
