A smaller sized Crambus (19-23 mm wingspan).

The hindwings are pale smoky with white fringes. The male genitalia are illustrated in Landry (1995). Similar to C. whitmerellus but longitudinal median line narrow, sharp pointed at apex, and lacking a tooth below.
Diurnal and comes to light. Single brooded. Apparently associated with marl fens. These areas are few in number and some have been drained. The numbers of this species will decrease with time.
Apparently of limited distribution in specialized habitats in Alberta.
Presumably native grasses.
