Description
The wingspan is 36–44 mm. Head, collar and vertex of head reddish orange. Tegulae and forewings pale reddish brown. The forewings are extensively covered with a metallic golden shimmering surface. Only the costal field and hem are brown. Sub-basal, antemedial and postmedial waved lines very indistinct, fine and whitish in color. The sub-marginal line irregularly lunulate. The reniform and orbicular tain are small and white bordered. The unpatterned hindwings are grey brown, somewhat darker at the margin. The thorax is furry and with some hair tufts, the proboscis is well developed.
Larva bluish green with a few short dorsal hairs. There are slender dorsal white lines and a prominent lateral line.
Ecology
The moth flies from August to October, depending on the location.
The larvae feed on various herbaceous plants, including crops such as sunflower, Coreopsis, potato and soybean. In managing their population, phenylacetaldehyde, a volatile floral compound attractive to many lepidoptera and present in Canada thistle (Cirsium arvense), was found to be effective in trapping especially the females of the species.
