Polygonia faunus, the green comma, is a butterfly of the family Nymphalidae. Some authors split Polygonia faunus into the above-mentioned subspecies, on the basis of differences in the color of the underside and their distribution. However most authors consider them as regional variants. This species can be found in the boreal North America, from central Alaska south to central California and northern New Mexico. It is also present across the Great Lakes area to New England, the Maritimes and in the southern Appalachians. The green comma mainly occurs in forests, mountain woodlands, near streams and in canyons.
The wingspan of Polygonia faunus can reach about 45–64 mm. These usually uncommon butterflies show extremely ragged wing edges. They are geographically rather variable. The upperside of their wings is reddish brown with wide dark borders. The hindwing border contains a row of yellow spots. The underside of the wings is grey-brown, but... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green Comma sighting in Calgary on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 136th most-seen of the 256 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and May
In those months about 10% of wildlife watchers report a Green Comma in Calgary on a given day, against under 5% in March–April and June–January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Green Comma sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Green Comma sightings, Calgary ranks 3rd at under 5%. The best odds are in Anchorage (United States, about 10%) and Edmonton (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Comma is recorded against all the insects logged in Calgary (14 verified sightings), 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.
