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 →

Rare
Under 5% of wildlife watchers report a Hoary Comma sighting in Great Bear Rainforest on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 200th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March to May
In those months about 10% of wildlife watchers report a Hoary Comma in Great Bear Rainforest on a given day, against under 5% in June to February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Hoary Comma sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
11th of 11
Of the 11 parks where we can rate Hoary Comma sightings, Great Bear Rainforest ranks 11th at under 5%. The best odds are in Wrangell-St. Elias National Park (United States, about 20%), Rocky Mountain National Park (United States, about 20%) and Glacier National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Hoary Comma is recorded against all the insects logged in Great Bear Rainforest (5 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.
