General Description
provided by University of Alberta Museums
A medium-size moth (3.1-3.8 cm wingspan) with elongate shining grey and pink forewings. The forewings have an egg-shaped pink basal patch capped with a dark blackish streak. Central areas of the forewings are dark grey-brown, with a prominent silver two-part stigma, comprised of a u-shaped segment and a separate elongate silver spot. The darker central area is continued as a blackish streak running almost to the apex. The terminal area above the streak is pink and grey, as is the area around the anal angle. Hindwings are dull grey-brown with an indistinct pale median band and a moderately checkered fringe. Antennae are simple and the sexes are similar. The only species even remotely resembling this moth is the much larger and differently patterned Euthyatira pudens.

Eosphoropteryx thyatyroides: Brief Summary
provided by wikipedia EN
Eosphoropteryx thyatyroides, the pink-patched looper moth or pink-tinted beauty, is a moth of the family Noctuidae. The species was first described by Achille Guenée in 1852. In North America it is found from Nova Scotia and northern Ontario south to Minnesota, Michigan, Ohio and along the Appalachians from Maine to eastern Tennessee and western North Carolina; and to the west, it occurs from central Alberta and southern British Columbia, south in the Cascades to southern Oregon, and in the Rocky Mountains to northern Idaho.
The wingspan is 31–38 mm. Adults are on wing from July to August in Alberta and from June to early August and mid-October in the Great Smoky Mountains National Park.
The larvae feed on Thalictrum dioicum and Thalictrum polygamum.
