General comments:
Extremely local resident.

The absence of this moth from great swathes of the two counties is genuine. It is very locally distributed in woodlands with young birches, apparently preferring trees in the sapling stage. Southern Hertfordshire and northern Middlesex are currently the best areas to look for it, but there is some evidence of loss from several sites.

Retained Specimen / Photograph will be Required.
