Common NameNorthern Arches SeasonalityAdults fly in June. IdentificationThe forewing is mottled shades of grey, with a pale white-grey antemedian (AM) and postmedian (PM) band. The PM band is often chestnut brown. Prairie populations are dimorphic, with females exhibiting a comparatively uniform, unbanded light grey forewing. The hindwing is cream white with a wavy black PM and arginal band. The black discal crescent is joined to the PM band. Similar to D. petricola, but slighlty larger and lacks the black veins of the ventral forewing margin. The nominate susbspecies occurs in the boreal and mountain region, while heathi occurs in the prairies. These two may be different species, more work is needed in areas where the ranges overlap or abutt.

Scientific Name Drasteria hudsonica Common Name Northern Arches Habitat In or near dry, open coniferous woods. Seasonality Adults fly in June. Identification

The forewing is mottled shades of grey, with a pale white-grey antemedian (AM) and postmedian (PM) band. The PM band is often chestnut brown. Prairie populations are dimorphic, with females exhibiting a comparatively uniform, unbanded light grey forewing. The hindwing is cream white with a wavy black PM and arginal band. The black discal crescent is joined to the PM band. Similar to D. petricola, but slighlty larger and lacks the black veins of the ventral forewing margin. The nominate susbspecies occurs in the boreal and mountain region, while heathi occurs in the prairies. These two may be different species, more work is needed in areas where the ranges overlap or abutt.

Life History Adults are day-active, but also come to light. Conservation Not of concern. Diet Info In Alberta, larvae of the mountain populations feed on Buffaloberry (Sheperdia canadensis) (Prentice 1962). Range Alaska to Manitoba, ND, SD, and NE south to NM in the Rockies (Richards 1939).
