scientific name    Crambus perlella    

Native and other grasslands.

July to August.

A medium sized Crambus (20-24 mm wingspan). Forewing pure silvery white, lacking a discal stripe. Hind wing also pure white. North American material belongs to the subspecies innotatellus Wlk. No other crambid has these features, but a tortricid, Eana argentana, is superficially quite similar. The latter, however, has labial palps that are only the length of the head.

life history
Diurnal and comes to light. The immature stages have been described by Felt (1894). Scholtens (1996) states that it is "one of the weedy Crambus species in northern Michigan". Common in the prairies, aspen parkland and foothills in Alberta.

Common to abundant, of no concern.
