scientific name    Nepytia canosaria    

common name     False Hemlock Looper

Coniferous boreal forest.

Adults fly in late August and September in Alberta.

Wings grey-white heavily dusted with dark grey, median area slightly darker and bordered with scalloped, prominent AM and PM lines. Discal spots large. Slightly darker and smaller than the similar Cingilia caternaria. N. freemani is very similar, but lacks the yellow scales at the top of the head of canosaria; the ranges of the two do not overlap, with freemani strictly a foothills/mountain species in Alberta.

life history
The caterpillar is boldly striped with green and yellow, a pattern helping it to blend in to the needles of its coniferous hosts. Pupates in a flimsy cocoon among host foliage. Adults are both diurnal and nocturnal (McGuffin 1987).

Not of concern.

diet info
Larvae feed on conifers, particularly balsam fir (Abies balsamaea) and white spruce (Picea glauca).

Northeastern Alberta east to Nova Scotia and Newfoundland, south through New England.
