The acutely-pointed forewing is light grey with medium grey shading in the median and basal areas. Fine black lines border these areas and scattered black dots can be found throughout parts of the wing. The hindwing is light grey and paler towards the base.

life history
Poorly known but in other species of this genus the larvae feed in the spring and go into a pupal diapause through the drier parts of the summer. Pupation occurs in leaf litter or in the soil within a cocoon which is unusual for the subfamily Tortricinae. The ovipositor is modifed to scrape up debris and deposit it on the eggs. (Powell 1980)

conservation
Not of concern.

diet info
The larva feeds on currants (Ribes sp.). (Powell 1980)

range
This species is known from the Northwest Territories and British Columbia, east to Saskatchewan and south to extreme northern California. (Powell 1980)

This species grades into D. macdunnoughi. (Powell 1980)
