|scientific name Scopula cacuminaria |
common name Frosted Tan Wave
The only Alberta specimen to date was taken on shrubby native grassland on the floodplain of the South Saskatchewan River.
The only Alberta specimen was collected on July 20.
A small (1.8-2.3 cm wingspan) creamy white to very light tan moth with somewhat pointed forewings and a pointed margin on the hindwings. The wings are speckled with black dots, forming a loose median band with heavier spotting on the outer half of the wings, usually forming dark patches in the anal-angle areas of both sets of wings. There are also a series of black spots on the dorsal abdomen. The small size and the distinctive pattern of black speckling will separate it from other species of Scopula.
Poorly known. Adults are nocturnal and come to light.
Uncommon in Alberta, but a widespread species. No reason for concern.
Apparently polyphagous; recorded hosts include lettuce and dandelion (Covell, 1984); and Asteraceae (unknown).
Across southern Canada from the Maritimes to southern BC, south to Texas.
The first (and only) Alberta specimen was collected in southern Alberta in 2005. It was known previously from both Saskatchewan and British Columbia
