The GREEN-BRINDLED CRESCENT moth is more brown than green, especially the melanistic one, (A. o. ab capucina).
Many thanks to Martin Starnes for these photos above which show the beautiful green highlights and the "crescent". Wingspan 35-45mm; UK flight time Sep-Nov.
The BRINDLED GREEN moth is a little like (and related to) the Merveille du Jour
with its mottled green colour. Wingspan 32-39mm; UK flight time Aug-Sep.
