|scientific name Mompha idaei |
Mainly in open areas in boreal forests where Fireweed grows.
June and July; also in May in other provinces. The larva is active from late summer until April (Forbes 1923; Koster & Sinev 2003).
The forewing is dark brown and eight to ten millimetres in length. Two dark brown scale tufts with silver tipped scales are visible on the inner margin in the median and postmedian area, with the latter often more distinctive. Paler markings vary from straw to light brown and is usually present along the inner margin, but often elsewhere as well. The hindwing is light brown and the remainder of the body is dull brown as well.
The larva bores in Fireweed and the adult is most likely active early in the morning, rarely coming to lights.
Probably of no concern.
Under the bark of the rootstock of Epilobium angustifolium and E. latifolium (Koster & Sinev, 2003).
Holarctic, in North America transcontinental in the boreal forest south to Colorado and Washington D. C.
