Species Details

Enypia griseata

University of Alberta E.H. Strickland Entomological Museum Read more about this collection »

Common NameMountain Girdle SeasonalityLate July to mid Augus in Alberta. IdentificationA mid-sized, grey geometrid with variable grey speckling; median band slightly darker, broad and heavily scalloped. Hindwing paler, with a faint PM line. Discal spot black, not white as in Caripeta species. Very similar to Nepytia species (particularly N. freemani), but in Enypia the forewing PM line comes closest to the wing margin near the apex, where it joins the costa, while in Nepytia the PM line is nearest the wing margin in the subapical (not apical) area. E. griseata has the discal spot well separated from the AM band, in venata the AM line jogs out to the discal spot.

The larva is stout and somewhat tapered at the ends, resembling a cutworm. Mature larvae are green with two white subdorsal stripes. Fourth instar larvae overwinter, and resume feeding in the spring (Duncan 2003). Adults are nocturnal and come to lights.
Conservation Not of concern. Diet Info Larvae are polyphagus on conifers, feeding on Douglas-fir (Pseudotsuga), spruce (Picea), and pine (Pinus), cedar (Thuja) and fir (Aibes) (McGuffin 1987). Range Central BC and southwestern Alberta south to AZ (McGuffin 1987).
