scientific name    Olethreutes quadrifidum    

Brushy or wooded areas with Red Osier Dogwood (Cornus stolonifera) and Chokecherry (Prunus virginiana).

Alberta material has been collected from June 21 to July 13.

A Tortricid moth of the subfamily Olethreutinae and tribe Olethreutini. Formerly in the genus Exartema along with the related species punctana and quadrifidus but now in the large genus Olethreutes. These three species all have wings that are olivaceous brown in color with somewhat darker apical and mid costal patches, wingspans in the 16-20 mm range, fly at the same time and have similar food plants. The fore wings of this species differ from punctana by lacking a dark basal patch and discal spot, and from inornatana by having a fine line of white scaling following the fold. Like punctana, the male genitalia have a digitus near the cucullus while punctana and inornatana have a digitus projecting from the neck of the harpe near the sacculus. The male genitalia are illustrated in both Heinrich (1926) and Miller (1987).
