Common NameClover Looper, Range Grass-moth SeasonalityAdults are on the wing in Alberta from early May through mid September. IdentificationA medium-size (3-3.2 cm wingspan) brownish grey (male) or brown (female) moth active both during the day and night. The forewing of the male is crossed by two the antemedian one running obliquely to the lower wing margin and touching or almost touching the vertical postmedian band near the lower margin. Crassiuscula is smaller (particularly the small spring brood specimens formerly treated as sp. distincta) and less "crisply" marked than the similar C. erechtea. The female is brown, is a bit larger and has more diffuse marking than does the male. Some larger male specimens may be very difficult to separate from C. erechtea, but these can be identified by checking the genitalia, which differ greatly in the two species.

Life History This moth is somewhat unusual in that it is active both during the day and at night. There are two or more broods per year, with an early brood of smaller adults appearing in May. Conservation A common, widespread species; no concerns. Diet Info No Alberta data. Elsewhere the larvae are reported to eat grasses (Gramineae) (Rockburne and Lafontaine, 1976), clover (Trifolium), lupines (Lupinus) , and grasses (Covell, 1984). Range Found throughout most of the USA and Canada; in Canada from the maritimes west to BC and north to James Bay and Yukon. Throughout most of Alberta, from the Milk River to the Caribou Mountains.
