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 →

With luck
About 10% of wildlife watchers report a Hoary Comma sighting in Sequoia and Kings Canyon National Parks on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 161 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–April, June and August
In those months about 20% of wildlife watchers report a Hoary Comma in Sequoia and Kings Canyon National Parks on a given day, against under 5% in November 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.
5th of 11
Of the 11 parks where we can rate Hoary Comma sightings, Sequoia and Kings Canyon National Parks ranks 5th at about 10%.

GBIF citizen-science records
It is estimated from how often the Hoary Comma is recorded against all the insects logged in Sequoia and Kings Canyon National Parks (28 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.
