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.
