scientific name    Archips purpurana    

common name     Omnivorous Leafroller

Found mostly in the Prairies in Alberta, but can be found in many open or shrubby areas.

Late June to July (Chapman & Lienk 1971).

The adult is easily recognized by the strongly sinuous margin of the costal margin. The forewing is light to dark purplish brown with darker fine brown to reddish brown thin lines and reticulations. The lines in the basal and median areas are more distinct than the others and sometimes border more darkly shaded areas. The edge of the costa and fringe is typically darker as well as a small thoracic scale tuft. The similar Choristoneura rosaceana has a less sinuous costa, is normally larger and has relatively longer wings with more distinct banding. The late instar larva is pale green with a faint darker green dorsal stripe and sparse long setae throughout. The head is black or brown and the thoracic shield is ringed with black or brown along the posterior and lateral edges that fades to green towards the anterior. The distinctive pupa is whitish green with dark bars on its back (Chapman & Lienk 1971).

life history
The larva folds the edges of a leaf together to form a shelter (Razowski 1977). The larva probably over winters in the middle instars amongst leaf litter or in a hibernaculum on shrubs (Chapman & Lienk 1977).

Of no concern.
