|scientific name Anterastria teratophora |
common name The Grey Marvel
In Alberta it has been collected only in riparian meadows in the aspen parklands region.
Adults in late May and June.
A rather small (approx. 2.5 cm. wingspan) dark broad winged noctuid moth. Forewings and thorax very dark brown. Normal markings present but indistinct. The only prominent markings are the large, white ringed and partially white filled reniform spots. There is also some white scaling along the costa beyond the reniform. Hindwings dirty white to light grey-brown, darker toward the outer margin. Antennae simple and sexes alike.
Poorly known. There is a single brood.
Reported larval hosts include mint (Mentha) and bergamont (Monarda), in the Mint family (Lamiaceae).
Quebec west to central Alberta, south to Florida and Arizona.
This little moth appears to be rare; it is encountered infrequently, and rarely is more than a single specimen found. Consequently we do not know a lot about it. Until recently it was placed in the genus Erastria in the subfamily Acontiinae along with Pseudeustrotia carneola. Both are primarily eastern species found in mesic meadows.
