My identification of
this species was initially based on comparison of my photos with specimens
in the Canadian National Collection in Ottawa, to which access was kindly
arranged by Dr. J. Donald Lafontaine of Agriculture Canada. My thanks
to Dr. P.T. Dang of the Canadian Forest Service for confirming the
identification for the actual specimen illustrated at left above.
moffatiana is one of four species of Proteoteras known to occur
in Ottawa. When fresh, it is immediately distinguishable from most
other members of the Tortricidae family by its green forewings; older
specimens do not always retain as clear a green color, as is evidenced by
the specimen at right above, and many of the collected specimens I have seen
have faded to a faintly greenish gray. Blackish streaks or smudges
extend from the base of the forewing to a raised "bump" of scales
at about a third of its length. An irregular blackish line extends in
a semicircle beginning at approximately the mid-point of the costa and
ending near the apex. Short stripes of green, dark gray to black and
near-white occur along the costal edge in a pattern characteristic of many
species of Tortricidae. The wing length is in the order of 8 mm. There is a pale green raised bump of scales at
the back end of the thorax.
According to various Internet sources, the
larvae of Proteoteras moffatiana are bud miners on sugar maple.
