Common NameSpotted Grass Moth, Yellow Snout-moth SeasonalityAdults are on the wing July to mid-August. IdentificationA small (1.5-1.9 cm wingspan) broad-winged light yellow or pale tan moth, with the median line forming a wide, elliptical brown patch near the costa, covering two small purple reniform dots. The fine, dark brown antemedian and postmedian lines swing out toward the apex in parallel. The terminal area and fringe shade to dark brown, and there are scattered dark scales over the remainder of the forewings. The hindwings are only slightly paler than the forewing ground, darker shaded toward the margin, and with a faint median line. The antennae are simple and both of the sexes are similar.
