McGuffin (1972) describes the immature stages. Adults come to light, but are also easily flushed during the day. This species is usually associated with bearberry (Arctostaphylos uva-ursi) in dry pine woods and along south-facing slopes.
Conservation Not of concern. Diet Info
Primarily heaths (Ericaceae) such as Vaccinium (Wood 1951); associated with bearberry (Arctostaphylos in Alberta. Other reported hosts include trembling aspen (Populus tremuloides), paper birch (Betula papyrifera)…
Primarily heaths (Ericaceae) such as Vaccinium (Wood 1951); associated with bearberry (Arctostaphylos in Alberta. Other reported hosts include trembling aspen (Populus tremuloides), paper birch (Betula papyrifera) and buffaloberry (Sheperdia canadensis). Aspen and birch are probably only occasional or accidental hosts, as M. brunneata was not reported from extensive collections from these plants by the Forest Insect Survey (Prentice 1963).
Range NFLD and NS west to Alaska and BC; south to Massachussettes, Michigan and Wyoming; also n. Europe, Siberia and Japan.
