Synonyms and other taxonomic changes
Papilio chariclea Schneider, 1794. Type locality: Lappland
Boloria chariclea (Schneider)
Clossiana chariclea (Schneider)
Explanation of Names
Includes montinus as a subspecies, following the classification of Opler and Warren and All-Leps (see discussion in Taxonomy Forum). Many authors consider B. montinus to represent a distinct more southerly species, and some still use the Eurasian name B. titania for this "other species". In this sense B. chariclea is more northerly in distribution. There is some merit to this separation, as the two types overlap in distribution and sometimes occur in the same area while remaining distinctly different. The names boisduvalii, grandis, and rainieri belong to the more southerly type.
While the subspecies helena & ingens are generally asigned to the southern "montinus type", they are rather distinctive, resemble the more northern "Arctic type" in some ways, and could perhaps be considered to make up yet a third "type".
Numbers
9 subspecies listed at All-Leps, with subspecies chariclea occurring only in the Old World
Size
wingspan 31-39 mm in United States (nearctica.com); 32-44 mm in Canada (CBIF)
Identification
Adult: upperside of wings orange with black spots, bars, and chevron-shaped markings, similar to many other Lesser Fritillaries.
The hindwing underside of the two boreal forest subspecies (grandis and rainieri) is purplish or reddish-brown with a broken yellowish to rust-colored band across the wing; it has white marginal spots capped with black chevron-shaped marks and a row of black spots above these.
The hindwing underside of the two tundra subspecies (arctica and butleri) has a distinct white band (sometimes silvered) across the middle, and the black submarginal spots and chevron marks are reduced or absent.
The New Hampshire subspecies montinus is dark rusty brown with no purplish markings.

Larva: body gray with black stripes and orange spines
Range
Circumboreal
Alaska and all of Canada, including arctic islands; extends into the continental US in Maine, New Hampshire, Minnesota, Washington state, and south in the Rockies to New Mexico (see distribution maps for Canada and continental United States)
Habitat
Varies according to subspecies and location, but includes arctic tundra, taiga (boreal forest), acid bogs, and moist alpine meadows.
Season
Adults fly from June to August (one brood).
Food
Larvae feed on scrub willow, violets, Western Bistort (Polygonum bistortoides), and blueberry.
Life Cycle
It takes two years to develop in the colder parts of its range, but can be found every year in most areas.
Remarks
In the arctic, the western mountains, and in some bogs, it is the most abundant Lesser Fritillary.
In New Hampshire, there's no mistaking this species for any other fritillary, because of its geographic location atop Mount Washington and several other peaks in the White Mountains.
See Also
In Canada and the western US, the Freija Fritillary (Boloria freija) has a black-and-white scalloped band and an elongate white triangular patch on the hindwing underside (see two images at CBIF)
Other Lesser Fritillaries have different markings on the hindwing underside
