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.

Unknown. No Alberta data. The only reported host is Trumpets or Pitcherplant (Sarracenia flava) (Covell, 1984).

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…
