Common NameDestructive Prune Worm SeasonalityAll specimens in the E. H. Strickland museum have been collected in July and August, but the moth may occur in June as well, probably dependent on the spring and early summer weather. IdentificationA fairly small micro moth (wingspan > 25 mm), with a slender body and fairly broad wings. The forewings a triangular, narrow at base and broad at apex. The ground color of the forewing is gray dusted with white scales, with a conspicuous bi-colored brown and white basal cross-band, a small elongate discal spot, and a blackish and white apical zigzag band, the latter often with distal reddish-brown shading. The hind wings are broad and white with grayish margins.

The hind wings are broad and white with grayish margins.
Life History The moth over winters as small larva on the host plant. It pupates in early summer and emerges as adult in mid and late summer. In north-western USA the moth can sometimes be a pest in prune orchards. Conservation Little is known about the status of A. tricolorella in Alberta, but it is not likely to be of any conservation concern. Diet Info The larvae generally feeds on buds and fruits of the genus Prunus (cherries and plums), but may feed on a variety of members of the rose-family such as Mountain Ash (Sorbus americana). Range Widespread in southern Canada and northern USA. All specimens in the E. H. Strickland museum have been collected in Edmonton, but the moth likely occurs southern and central part of the province.
