My thanks to Dr. J. Donald Lafontaine of Agriculture Canada for confirming my identification of the specimens illustrated at top left and center left above.

Crocigrapha normani, also known as Norman's Quaker, has a brown to reddish brown forewing, occasionally peppered with specks of black as in the photo at center left.  The double basal, antemedial and postmedial lines have a whitish filling, usually edged with dark gray to black.  In the photo at center right, these lines are extremely clear, but the black edging is virtually absent in the photo at center left.  The basal and antemedial lines are relatively straight, but the postmedial line bends sharply outward just below the costa, then curves gently across the wing to the inner margin.  The pale-rimmed orbicular and reniform spots usually have a filling slightly paler than the ground color, with near black filling in the lower end of the reniform spot.  In the center left and bottom photos, however, most of the filling is the same as the ground color.  The subterminal area of the wing is somewhat lighter in color, with a light gray patch at the costa near the apex.  The hindwing is whitish, with some gray-brown shading along the outer margin towards the apex, and a pale whitish fringe.  For this species, Covell (1984) indicates a wingspan from 3.5 to 4.0 cm.

According to Handfield (1999), the larvae of Crocigrapha normani have been reported to feed on a very wide variety of trees and shrubs, including birch, maple, elm, ash, willow, oak, poplar, hop hornbeam, cherry, hazel, apple and many others.  For my general area, he indicates an adult flight season from before mid-April into the second half of June.
