|scientific name Raphiptera argillaceella |
June and July (Bowman 1951).
A small crambid (10-15 mm wingspan) with mouse gray color. The forewing has a small hook (produced) at the apex similar to a number of Crambus species; and a large, longitudinal, white, slightly silvery, median stripe which ends in a slightly bidentate tip, beyond which there is a white chevron and a triangular patch in the wing tip; there are three dashes from the subterminal line to the terminal line where they end as dark dots. The male genitalia are illustrated in Landry (1995). The genus is separated from Crambus by wing venation.
