Distribution:

Subspecies feildeni is the equivalent of ssp. polaris in North America. It occurs in Alaska and the Canadien provinces of Nunavut, NW Territory and Yukon.

Stages in development:

Larva. The foodplant of the larva is supposed to be Oxyria reniformis Hook (=O. digyna (L.) Hill), which is common on the type locality, whereas Rumex is absent (M┤Lachlan 1878).

Diagnosis:

Following M┤Lachlan (1878), feildeni differs from typical L. phlaeas (LinnÚ, 1761) and americanus (=L. hypophlaeas (Boisduval, 1852)) in the "brilliant copper-colour of the upperside of the anterior wings, being much less fiery and more subdued and with brassy reflections (especially in the ), so that the colour might almost be termed brassy rather than coppery; the spots normal in number and position, but smaller; the dark border is narrow and silky greyish black with grey fringe, the dark costal margin scarcely indicated: in the posterior wings the ground is of the same silky greyish black as in the border of the anterior, the pale submarginal band pale orange, with occasionally the faintest indications of bluish spots above it."
