With luck
About 10% of wildlife watchers report a Variable Checkerspot sighting in Yosemite National Park on a given day, based on 54 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 227 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Variable Checkerspot in Yosemite National Park on a given day, against under 5% in July to March, the lowest months. That is one of Yosemite National Park's driest months, with about 50 mm of rain against 220 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Variable Checkerspot sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Variable Checkerspot sightings, Yosemite National Park ranks 3rd at about 10%. The best odds are in Joshua Tree National Park (United States, about 30%) and Sequoia and Kings Canyon National Parks (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Variable Checkerspot is recorded against all the insects logged in Yosemite National Park (54 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.
