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.
Conservation Not of concern. Diet Info The principal larval host is Douglas-fir (Pseudotsuga menziesii), rarely other conifers (McGuffin 1987). Range Southern BC and extreme southwestern Alberta south to WA, ID, MT and UT (McGuffin 1987, Duncan 2003).
