Both photos are of the same specimen.
My initial identification of Choreutis pariana was based
on Internet resources, and subsequently confirmed when I showed the specimen to
Dr. Jean-François Landry of Agriculture Canada, to whom my thanks. For
further information I have relied on Covell (1984) and Forbes, William T.M., The
Lepidoptera of New York and Neighboring States, Primitive Forms,
Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell University,
1923). This species was introduced to North America from Europe in about
1917 (Covell, 1984).
Choreutis pariana has a brown forewing with somewhat
diffuse dark brown lines and paler shades that suggest the pattern of a very
small noctuid moth. The basal area is gray-brown with reddish reflections,
bounded by a zigzag antemedial line of dark brown. The inner half of the
median is gray brown. A whitish shade in the outer half of the median
extends into the subterminal area, and against this paler shade it is possible
to make out a brown postmedial line. The area along the outer margin is reddish
brown. The fringe is also reddish brown, but with a touch of white at the
apex. Forbes (1923) indicates a wingspan of 10 mm for this species; Covell
(1984) suggests a slightly greater wingspan.
The larva of Choreutis pariana feeds on apple and
hawthorn, and was termed by Covell (1984) the Apple-and-thorn Leaf Skeletonizer.
Forbes indicates that the adult moth flies in August. My record of 30
April is an unusual date for this species in the Ottawa area, and may indicate
that this moth overwinters here as an adult (J.-F. Landry, pers. comm., May
