Distribution and Abundance:  Common.

Primary Habitat:  General occurrence.

Flight Period:  Almost entirely single brooded in July with a few moths appearing as a very partial second generation in the autumn.

Observations:  Recently the incidence of moths appearing in the autumn has increased markedly. I have recorded singletons at light in September and October in five out of the last ten years in my own garden. Historically, this has always been a rare occurrence in the county with records only from 1945 and 1947.

First Record: 1858, Green.
