scientific name    Acleris logiana    

common name     Black-headed Birch Leafroller

Likely occurs throughout the boreal forest, foothills and lower elevations of the mountains in AB, wherever birch is present.

A small (approx. 2.0 cm wingspan) moth with whitish or pale grey squared forewings and grey hindwings. Forewing markings variable, with dark grey or rust markings indicating the inverse costal triangle usually reduced to dark spots on the costa and in particular the dark discal dash at the apex of the "triangle". A few small spots or dots of the same color elsewhere on the forewings, in particular in the basal area. There is a series of raised white scales that form an inverse arc across the forewings when forewings when at rest. The dirty white or pale grey forewings with the few dark markings on the forewing will help distinguish this little moth.

life history
Larvae are solitary leaf-rollers. The primary hosts are birches (Betula); also recorded from Viburnum and alder (Alnus). Adults in fall (late Aug. early Oct.) and again in spring (mid Apr. early June), apparently hibernating. Adults come to light.

Holarctic. Europe east across the southern USSR to Japan; widespread in the boreal forest of North America, south in the mountains in both the east and west.

One of the palest of the Acleris leafrollers, and like many members of the genus highly variable in the appearance of the adults. The adult illustrated above is a specimen from Edmonton. The genitalic illustration is from Razowski (1966).
