[edit] Description
The wings are orange-brown with dark markings. The color of the hindwings are orangish-brown with a tan postmedian band followed by a row of round silver spots. The length of the forewings is 20–24 mm. The butterfly may be threatened by bog hydrology.[1] The males search for females in wet areas.[2] The butterfly has the subspecies triclaris (from Newfoundland to Alberta), nichollae (Alberta), and denali (Alaska and northern Yukon). The butterfly flies close to the ground.[3] The species is listed as vulnerable.[4] They eat nectar from flowers including Labrador tea and goldenrod.[2] The species flies from the end of May till the beginning of August.[4] The butterfly can be identified form similar species by looking on the hindwing underside; this species is the only one with a row of silvery submarginal spots.[5]
[edit] Habitat
It is found throughout the north-temperate region of the Northern Hemisphere[5] including the Balkan Mountains of Bulgaria and one isolated population in Serbia.[6] The species is not mentioned in the Red Data Book of Serbian butterflies because it was not known to be in the country at the time of it being published.[6] The species is commonly found in open acid bogs in areas that are moist.[1] It can also be found in moist tundra and willow seeps.[2]
[edit] Caterpillars
The eggs are laid in groups of 2 to 4 under the host plant leaves.[2] When the eggs hatch in 7 to 8 days and after hatching, they feed on the underside of the leaves on the host plant. Caterpillars in Colorado and Wyoming are reddish-brown with red spines, with third or fourth instars hibernating. The caterpillars feed on Viola species and willows.[5] The caterpillars can be found from April to June.[7] The caterpillars are silver-gray with white dots.[3]
