scientific name    Stiria rugifrons    

Dry open areas; disturbed sites such as old fields, eroding badlands and sand dunes.

Adults have been collected in Alberta from mid-July through mid-August.

A rather large (3.2-4.2 cm wingspan) bright yellow moth with red-brown markings. The forewings are yellow with a large spot-like basal dash, a large spot midway along the lower margin, and a dark terminal band, all reddish-brown. The hindwings are white, suffused with red-brown scales on the outer half in the males, and over most of the wing in females. The bright yellow color and bold pattern is unlike any other Alberta moth. The larvae are described in Poole, 1995

life history
Adults are nocturnal and come to light. There is a single brood each year, with adults flying in late summer. Like the other members of the subfamily, the larvae feed on the flowers and seeds of their host plants.

Uncommon to rare at the northwestern edge of their range in Alberta.

diet info
No Alberta data. Larvae have been found on the sunflower Helianthus microcephalus in Ohio (Poole, 1995), and native sunflowers are the probable host in Alberta.

Northern Florida north to Virginia and southern Ohio, west to southern Saskatchewan and Alberta, Wyoming, Colorado and west Texas. In Alberta it has been collected from Lethbridge north and east to the Wainwright dunes.
