|scientific name Macaria brunneata |
common name Ochre Granite
Open coniferous forest in the boreal and mountain region; old dune complexes.
The peak adult flight period is mid July.
This is the only Macaria with uniform ochre-brown wings; the males exhibit variably prominent dark transeverse lines, with the PM and AM lines sometimes fully developed. The three to four dark wedges along the forewing costa are not always present. Females are a lighter tan colour with well defined dark basal, AM and PM lines.
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.
Not of concern.
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).
NFLD and NS west to Alaska and BC; south to Massachussettes, Michigan and Wyoming; also n. Europe, Siberia and Japan.

I''ve collected what appears to be Macaria brunneata, on 10.07.03, at a wooded farm site, north of Innisfree, Alberta. It flushed up during a casual butterfly, plant, and bird survey. I''ll send a photo later.
