|scientific name Choristoneura zapulata |
Not commonly collected but most Alberta specimens have been collected from dunes.
Late June to Mid August.
The forewing is straw yellow to light brown with abundant darker brown fine reticulations throughout. Bands in the basal, median, and upper subterminal areas are distinctly edged in brown and may be shaded with darker brown, especially towards the costa, though the amount of shading varies from none to fully shaded. The hindwing is straw yellow with a light grey inner half.
This rarely collected species is similar to the vastly more common C. rosaceana but lacks the small triangular costal fold.
Unknown, many specimens in collections are misidentified.
The larva feeds on Ceanothus, Sweet-fern (Comptonia peregrina), blueberry (Vaccinium sp.), rose (Rosa sp.), strawberry (Fragraria sp.), clover (Trifolium sp.), Symphoricarpos sp. (Freeman 1958)
From British Columbia to Quebec, south to California, Illinois, and Pennsylvania.
