The hoary comma (Polygonia gracilis) is a species of butterfly, common in boreal North America from Alaska, across southern Canada to New England and the Maritime Provinces and south to New Mexico from the Rocky Mountains to the Pacific Ocean. The wings have a distinctive ragged edge.
Adult butterflies feed on tree sap and nectar from sweet everlasting (Gnaphalium) as well as other flowers. Caterpillars feed on shrub leaves including currant (Ribes), western azalea (Rhododendron occidentale) and mock azalea (Rhododendron menziesii).
The species survives the winter in the adult stage in diapause and mates and lay eggs in the spring. Butterflies emerge from their chrysalids in midsummer. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Hoary Comma is recorded against all the insects logged in Jasper National Park (9 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.
