Polygonia satyrus, the satyr comma, is a North American butterfly of the nymphalid family. It is primarily found in western Canada, where it is locally common. It bears a resemblance to Polygonia comma, the eastern comma, with which it is frequently confused.
Polygonia satyrus was first described by William Henry Edwards in 1869 from specimens collected in Colorado. Several names that were historically treated as distinct taxa, including P. marsyas, P. chrysoptera, and P. hollandi, have subsequently been regarded as synonyms of P. satyrus. Some authors previously considered marsyas to represent a distinct Pacific Northwestern subspecies, but breeding experiments and distributional evidence suggested that it represents a dark form of P. satyrus rather than a separate taxon.
Morphological studies have suggested a close relationship between P. satyrus and the eastern comma (Polygonia comma). Similarities in genital morphology, larval biology, host plant use, and wing pattern have led some authors to regard P. satyrus as a western subspecies of P. comma.
Polygonia satyrus belongs to the tribe Nymphalini within the family Nymphalidae. Phylogenetic studies place the species... Wikipedia →

Rare
Under 5% of wildlife watchers report a Satyr Comma sighting in San Francisco on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 737 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Satyr Comma in San Francisco on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Satyr 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.
7th of 8
Of the 8 cities where we can rate Satyr Comma sightings, San Francisco ranks 7th at under 5%. The best odds are in Edmonton (Canada, about 10%), Calgary (Canada, about 10%) and Vancouver (Canada, about 10%).
Same family: Nymphalidae
The closest relatives of the Satyr Comma that you can see in San Francisco (family Nymphalidae, Brush-footed Butterflies) are Monarch (about 30%), Red Admiral (about 20%) and Gulf Fritillary (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Satyr Comma is recorded against all the insects logged in San Francisco (23 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.
