IdentificationA small (2.7 – 3.0 cm wingspan) green moth with broad pointed wings. The wings are bright green. A prominent straight white line crosses both wings diagonally, from the forewing costa just short of the apex to lower part of the inner margin of the hindwing. A second similar line crosses the forewing only near the base. Male antennae bipectinate, female simple. Similar to Nemoria species, but the white line pattern is unique among Alberta moths.
