General comments:
Ubiquitous.

Willow Beauty is the most frequently reported geometrid moth in the two counties. Formerly double-brooded there is now a third generation of adults every year, but this is small and overlaps with the tail end of the second generation. Third brood adults are smaller than the norm - often excessively so.
