St. Williams Forest, Norfolk, Ontario, Canada
July 30, 2005
Size: wingspan about 25 mm
On fallen leaf in sandy deciduous woods. Has the look of a geometer but I couldn't find any images that matched. Closest guess was the Drepanid (hooktip) moth that doesn't have hooked tips: Northern Eudeilinia
but it's not very convincing.
Whatever this one is, it looks the same as the photo by Cindy Mead on this page
