With luck
About 10% of wildlife watchers report a Crimson-Ringed Whiteface sighting in Yosemite National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 116th most-seen of the 227 insects we can rate there. Over three days the chance rises to about 20%, 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 Crimson-Ringed Whiteface 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 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Crimson-Ringed Whiteface sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Crimson-Ringed Whiteface sightings, Yosemite National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Great Bear Rainforest (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Crimson-Ringed Whiteface is recorded against all the insects logged in Yosemite National Park (13 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.
