The western pine elfin (Callophrys eryphon) is a North American butterfly that ranges from British Columbia east to Maine and south to southern California, Arizona, and New Mexico. Males are brown and females are orange-brown, with both having bold patterned hind wings. The top of the wings have dark bars with a lighter chevron shaped margin. The body is 19–32 mm in length and has no tail.
This butterfly is found in natural pine woods and evergreen forests. In the northwest United States they are found nesting in lodgepole pines and can be seen perched on shrubs and smaller trees while searching for food or looking for a mate. The western pine elfin is seldom seen outside its natural habitat. They feed on flower nectar including wild blueberries, milkweed, and clover. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Western Pine Elfin is recorded against all the insects logged in Jasper National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
