|scientific name Nepytia freemani |
common name Western False Hemlock Looper
Montane coniferous forest.
Adults emerge in autumn and fly from August to October (McGuffin 1987
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 Cingilia caternaria.
N. freemani lacks the yellow scales at the top of the head of N. canosaria; the ranges of the two do not overlap, with freemani strictly a foothills/mountain species in Alberta.
The larvae are tan and rust coloured, with cream lateral stripes; they are occasionally abundant enough to cause visible defoliation of conifers in BC (Duncan 2003). Eggs are laid singly or in small groups on the host needles, where they overwinter. Larvae are illustrated in Ives & Wong (1988) and Duncan (2003), and all immature stages are illustrated by Klein and Minnoch (1971). Adults are nocturnal.
Not of concern.
The principal larval host is Douglas-fir (Pseudotsuga menziesii), rarely other conifers (McGuffin 1987).
Southern BC and extreme southwestern Alberta south to WA, ID, MT and UT (McGuffin 1987, Duncan 2003).
