Common NameYellow-cloaked Midget, The Half-yellow SeasonalityAdults have been collected in Alberta from mid June to mid July. IdentificationA small (1.8-2.4 cm wingspan) bright yellow and purple-brown moth. The head, thorax and basal half of the forewings are bright yellow, except for a small spot of purple-brown at the wing base. The sharply divided outer half of the forewing including the fringe is dark purple-brown, mixed with white scales in the apical area, giving it a slightly frosted appearance. The hindwings are light brown or white peppered with brown scales, which also line the veins and form a diffuse dark outer border. The hindwing fringe is brown on the basal half and white on the outer half. Antennae simple; sexes alike. Impossible to mistake for any other Alberta insect.

Range
New England south to Florida and Arizona; north to southern Manitoba and west to the southern interior of British Columbia. In Alberta it has been collected locally from the Milk River north to Lloyminster and…
