Further Information:
Autographa gamma (syn=Plusia gamma) is a migratory moth of the family Noctuidae. It is named for the silver Y-shaped markings (Y=Gamma in greek) on each of its forewings. The species is between 30-45mm in wingspan and the patterns on the wing vary considerably between specimens. This patterns aid in camouflauging the insect with the background (e.g. wood, bark, dry leaves, etc.) They feed on a wide variety of low-growing plants and have been recorded on over 200 different species including crops such as the garden pea (Pisum sativum), sugar beet (Beta vulgaris) and cabbage (Brassica oleracea). It migrates between countries in North Africa and those in North Europe including Iceland and Finland.
