White-veined Arctic - Oeneis bore
General Description
[From Ferris and Brown 1981; Scott 1986; Opler and Wright 1999; Glassber 2001; Guppy and Shepard 2001] Forewing 2.2-2.5 cm. Wings translucent, without eyespots. Uppersurface of female forewing often orange-tan in middle, male forewing with gray sex patch in middle. Undersurface light brown, veins of hindwing usually white, hindwing with dark median band outlined by basal and postmedian lines edged with white.
Phenology
One flight; mostly late June to early August, mid-June and July in western Arctic, alternating years except every year in Colorado and Wyoming (Ferris and Brown 1981; Scott 1986). Late June to mid-August (Glassberg 2001). June and July in British Columbia (Guppy and Shepard 2001).
Diagnostic Characteristics
Best determined externally by combination of wings translucent and without eyespots, undersurface of hindwing with dark median band outlined by basal and postmedian lines edged with white, the hindwing veins usually white.
Species Range
Montana Range
Range Descriptions
Native
Range Comments
Holarctic. In North America, throughout Alaska and Yukon, east north of treeline to Labrador and Greenland, isolated population on Mt. Albert, Quebec; also south in isolated populations in the Rocky Mountains of British Columbia, Alberta, Montana, Wyoming, Utah to southwestern Colorado (Opler and Wright 1999; Glassberg 2001; Guppy and Shepard 2001); to at least 3810 m elevation in Colorado (Brown 1957; Ferris and Brown 1981). Reported in Montana only in the Beartooth Mountains of Carbon and Stillwater counties (Kohler 1980; Stanford and Opler 1993), probably above 3048 m elevation. Locally rare to locally uncommon (Glassberg 2001).
Migration
Non-migratory.
Habitat
Tundra, taiga, grassy alpine slopes, rocky ridges, subarctic bogs, sedge meadow, hummocky tundra (Oosting and Parshall 1978; Ferris and Brown 1981; Scott 1986; Opler and Wright 1999; Glassberg 2001; Guppy and Shepard 2001). Habitat in Montana not described but probably occupies similar alpine terrain in Beartooth Mountains.
Ecological Systems Associated with this Species
- Details on Creation and Suggested Uses and Limitations
How Associations Were Made
We associated the use and habitat quality (common or occasional) of each of the 82 ecological systems mapped in Montana for
vertebrate animal species that regularly breed, overwinter, or migrate through the state by:
- Using personal observations and reviewing literature that summarize the breeding, overwintering, or migratory habitat requirements of each species (Dobkin 1992, Hart et al. 1998, Hutto and Young 1999, Maxell 2000, Foresman 2012, Adams 2003, and Werner et al. 2004);
- Evaluating structural characteristics and distribution of each ecological system relative to the species' range and habitat requirements;
- Examining the observation records for each species in the state-wide point observation database associated with each ecological system;
- Calculating the percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system to get a measure of "observations versus availability of habitat".
Species that breed in Montana were only evaluated for breeding habitat use, species that only overwinter in Montana were only evaluated for overwintering habitat use, and species that only migrate through Montana were only evaluated for migratory habitat use.
In general, species were listed as associated with an ecological system if structural characteristics of used habitat documented in the literature were present in the ecological system or large numbers of point observations were associated with the ecological system.
However, species were not listed as associated with an ecological system if there was no support in the literature for use of structural characteristics in an ecological system,
even if point observations were associated with that system.
Common versus occasional association with an ecological system was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species as represented in scientific literature.
The percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system was also used to guide assignment of common versus occasional association.
If you have any questions or comments on species associations with ecological systems, please contact the Montana Natural Heritage Program's Senior Zoologist.
Suggested Uses and Limitations
Species associations with ecological systems should be used to generate potential lists of species that may occupy broader landscapes for the purposes of landscape-level planning.
These potential lists of species should not be used in place of documented occurrences of species (this information can be requested at:
mtnhp.org/requests) or systematic surveys for species and evaluations of habitat at a local site level by trained biologists.
Users of this information should be aware that the land cover data used to generate species associations is based on imagery from the late 1990s and early 2000s and was only intended to be used at broader landscape scales.
Land cover mapping accuracy is particularly problematic when the systems occur as small patches or where the land cover types have been altered over the past decade.
Thus, particular caution should be used when using the associations in assessments of smaller areas (e.g., evaluations of public land survey sections).
Finally, although a species may be associated with a particular ecological system within its known geographic range, portions of that ecological system may occur outside of the species' known geographic range.

Food Habits
Limited information. Larval food plants include Carex and several species of Festuca (Scott 1986). Adults occasionally feed on flower nectar, including unidentified "yellow sunflower" (Scott 2014).
Reproductive Characteristics
Limited information. Females lay eggs singly on blades of host grass or sedge. Biennial; early instar larvae (L1-L2?) probably hibernate the first winter, L4-L5 instars hibernate a second winter (Scott 1986). Males perch and patrol throughout the day on grassy hilltops and hillsides as they seek females females (Scott 1975b, 1986).
