C041 Scoparia subfusca female

Crambidae, Scopariinae. Wingspan: 18mm.

Updated! Looking through my picture records, I now think that this is a female of the above species. Unfortunately, the reference book I have, "British Pyralid Moths" by Barry Groater has small pictures which are far from easy to identify from, but I am now seeing this is similar to specimens we have recorded in Cornwall.
