Rare
Under 5% of wildlife watchers report a Hoffmann's Checkerspot sighting in Yosemite National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th most-seen of the 227 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.
June and July
In those months about 10% of wildlife watchers report a Hoffmann's Checkerspot in Yosemite National Park on a given day, against under 5% in August to May, the lowest months. Those are among Yosemite National Park's driest months, with about 25 mm of rain a month against 220 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Hoffmann's Checkerspot sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Yosemite National Park, in our data
Yosemite National Park is the only park on Wallace's Line with enough records to rate Hoffmann's Checkerspot sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Hoffmann's Checkerspot is recorded against all the insects logged in Yosemite National Park (6 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.
