Rare
Under 5% of wildlife watchers report a Northern Checkerspot sighting in San Francisco on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 679th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Northern Checkerspot 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 Northern Checkerspot sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only San Francisco, in our data
San Francisco is the only city on Wallace's Line with enough records to rate Northern Checkerspot sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae

GBIF citizen-science records
It is estimated from how often the Northern Checkerspot is recorded against all the insects logged in San Francisco (5 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.
