Cydia latiferreana, previously called Melissopus
latiferreanus, is one of 13 species of Cydia recorded from the Ottawa
area (J. D. Lafontaine, pers. comm., 2001). My thanks to Dr.
Jean-François Landry of Agriculture Canada for his assistance with the initial
identification. Additional
information has been obtained from Internet resources and from Forbes, William
T.M., The Lepidoptera of New York and Neighboring States, Primitive Forms,
Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York: Cornell
University, 1923).
Cydia latiferreana has a light reddish brown forewing
with a stippled appearance, somewhat brighter in color along the costa and
towards the apex. A band of metallic scales crosses the wing in the medial
area, widening slightly at the inner margin. A second, thinner metallic
band crosses the wing at about 3/4 of its length, with a slight gap in the
middle. Beyond this band, several short metallic striae angle outward from
the costa, one of which curves, with some interruptions to cross the wing close
to the outer margin. Several lengthwise fine black streaks may be evident
near the anal angle, as in the upper right photo. Forbes (1923) describes
the metallic bands as lead-colored, but they appear brassy or golden under some
lighting conditions. Indeed, my first impression of this moth caused me to
think of it as the "cigar-band moth." The gray fringe, sometimes
with a metallic shine, is preceded by a fine dark terminal line. Forbes (1923) indicates a wingspan of
15 mm.
According to Forbes (1923) and other sources, the larva of Cydia
latiferreana, also known as the Filbertworm, bores into acorns and
hazelnuts. Forbes indicates an adult flight season in July and August,
with a (possibly partial) second generation flying in late September.
