|scientific name Heliothis borealis |
Open bogs, clearings and meadows in the boreal forest, foothills and mountain regions.
Adults are on the wing in spring, May - June.
A small (2.2-2.5 cm) diurnal moth. Forewing brown-black with a darker blackish basal area, a prominent dark reniform spot and a dark terminal margin. The hindwing is black with a wide creamy white central area.
A small, apparently rare day-flying moth. Like other members of the genus, probably using the buds, flowers and seeds of a number of species of low plants as hosts. Adults have been reported nectaring (?) at flowers, including Vaccinium sp., bearberry and willow catkins.
Although rarely encountered, there is no reason to believe this moth is in any need of protection.
It has been reared on Cerastrium in captivity. Other reported hosts include Kalmia and Larch, but specimens in captivity refused Kalmia and Larch is an improbable host for a member of this genus. Like other members of the genus, larvae feed on the buds, flowers and seeds of the host.
Quebec west to Alberta, and south in the mountains to southwestern Montana. In Alberta it has been found in the mountains and foothills from Calgary south.
