Rare
Under 5% of wildlife watchers report a California Digger-Cuckoo Bee sighting in Yosemite National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd 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.
July and September
In those months about 10% of wildlife watchers report a California Digger-Cuckoo Bee in Yosemite National Park on a given day, against under 5% in August and October–June, 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 noon and 3 pm
Across all the parks we cover, that three-hour window holds the most California Digger-Cuckoo Bee sightings with a recorded time, and nearly all 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 California Digger-Cuckoo Bee sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Apidae
The closest relatives of the California Digger-Cuckoo Bee that you can see in Yosemite National Park (family Apidae, Honey Bees, Bumble Bees, and Allies) are Yellow-Faced Bumble Bee (about 20%), Western Carpenter Bee (about 10%) and Urbane Digger Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the California Digger-Cuckoo Bee is recorded against all the insects logged in Yosemite National Park (5 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.
