|scientific name Catoptria latiradiella |
July and August.
A medium sized crambid (19-24 mm wingspan). Forewings chocolate brown with a silvery white discal stripe that is crossed by two diagonal dark brown lines; terminal line with a row of black dots. Crambus myellus Hbn. was formerly thought to be a synonym. Easily distinguished as there is nothing else like it in Alberta.
Diurnal and comes to light. Forbes (1923) states "caterpillar under moss; brown, with black head and cervical shield".
Uncommon, but of no concern.
No local information. The larvae of the closely related European species Catoptria permutatella feed on mosses (Bleszynski 1965).
A North American species said by Forbes (1923) to occur from Labrador to Pennsylvania and west to British Columbia. Reported from British Columbia by Dyar (1904) and Michigan (Scholtens 1996). In Alberta, reported from the Edmonton and Nordegg areas (Bowman 1951) and from the Canadian Shield (Macaulay & Pohl 2002).
