About the Sycamore Moth
The sycamore (Acronicta aceris) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is distributed through most of Europe, from central England south to Morocco. To the east it is found from the Near East and Middle East to western Asia.
The forewings of this species are pale to dark grey with rather indistinct markings apart from a thin black basal streak. The hindwings are white, sometimes with dark streaks at the margin. The wingspan is 40–45 mm. Forewing whitish grey; basal streak thin and interrupted: a black streak through outer line on submedian fold; hindwing white in male, greyish in female, the veins blackish. — ab. infuscata Haw.
