|scientific name Crambidia impura |
Stabilized sand dunes dominated by open jack pine forest.
Adults in Alberta in August and September.
Members in this genus are superficially similar to the grass moths (Pyralidae: Crambinae), but these generally have some markings on the forewing, and have conspicuously long palpi. There are several species of leaf-rollers (Tortricidae) that are very similar, but these have a pointed forewing apex and are smaller than Crambidia. C. impura is smaller than C. casta, and is light grey in colour, not white. Their ranges are currently not known to overlap in Alberta.
No information available.
C. impura is known from two disjunct populations. It occurs in the southern Rocky Mountain states, the Yukon and northern B.C. and Alberta. This species is known from the Peace River valley of B.C. (Troubridge & Lafontaine 1998), and should be watched for on the Alberta side.
