|scientific name Stiriinae |
Primarily xeric areas, such as desert and scrub and sandy areas.
Single brooded in Alberta, with adults on the wing mid-July through mid-August.
Large to small moths, and ranging from very drab to some of the most colorful North American moths. The external variability contrasts with a very conservative internal morphology. Two apparently synapomorphic characters for the subfamily appear to be the general shape and spine patterns on the male vesica, and the reduction of the spineret in the larvae to a small scale-like object (Poole, 1995).
The Alberta species are nocturnal and come to light. There is a single annual brood, probably over wintering in the pupal stage.
In Alberta (and Canada) rarely collected and known from only a few sites per species.
The larvae of all known species feed on the flowers and seeds of composites (Asteraceae).
North and Central America. A few species occur in eastern North America or reach southern Canada, but the vast majority are found in the American southwest and Mexico. Three species, Plagiomimicus expallidus (Grt.), P. spumosum Grt.and Stiria rugifrons Grt. reach southern Alberta.
