The photos at top left, top right and bottom left are all of the same specimen.
My identification of Amydria effrentella is based on
comparison with photographs on the web site "All Leps Barcode of Life"
at http://www.lepbarcoding.org/index.php and on the description of this species
in Forbes, William T.M., The Lepidoptera of New York and Neighboring States,
Primitive Forms, Microlepidoptera, Pyraloids, Bombyces (Ithaca, New York:
Cornell University, 1923).
Amydria effrentella has a light straw-yellow to buff
forewing with dark gray-brown markings and variable speckling. The costal
edge is punctuated by a series of short dark bars, somewhat variable along the
inner half of the costa, with four more regularly spaced bars from midpoint to
apex. Three larger dark patches occur along the middle of the wing, the
first near the base, and the other two at about 1/3 and 2/3 the length of the
wing. The dark patch at 1/3 of the way from the base seems often to extend
obliquely to the costa. Some specimens also show one or two dark spots or
bars in the lower half of the wing about halfway out from the base. A
terminal line of dark spots precedes the pale fringe. Forbes (1923)
indicates a wingspan from 15 to 25 mm for this species.
According to Forbes (1923), the adult Amydria effrentella
flies in June and August. He gives no information as to host plant(s) or
