Distribution and Abundance: Local.

Primary Habitat:  Woodland.

Flight Period:  Single brooded from May to July.

Localities:  Hazelborough Wood, Lings Wood, Spanhoe Wood and Easton Hornstocks.     

Observations: The species seems to prefer open birch woodland and in my experience was nowhere as plentiful as around the birch wood within Geddington Chase. Generally it seems to have become less common in recent years. My own field records show that I saw the moth in Northamptonshire in six years of the ten years to 1999 and only once in the past decade. In some localities the uniformly light greyish brown ab. obscura is as common as the typical form.

L.O.N.:  1905. Sywell, near Kettering, Farming Woods. Not uncommon at treacle.

First Record:  1882, Hull & Tomalin.
