In 3 days ~10% in a week ~30%
Calliopsis puellae is a species of bee in the family Andrenidae. It is found in Central America and North America. The species' type specimen was collected by Wilmatte Porter Cockerell and her great-niece, Lelah Milene Porter (1927–2001). It is now at Harvard University's Museum of Comparative Zoology. The species was named (as Spinoliella puellae) by Wilmatte's husband, Theodore Dru Alison Cockerell, who wrote:
The name S. puellae commemorates the very little girl who helped my wife to collect the specimens. Wikipedia →

Rare
Under 5% of wildlife watchers report a Calliopsis puellae sighting in Joshua Tree National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 164th most-seen of the 190 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.
April and May
In those months about 10% of wildlife watchers report a Calliopsis puellae in Joshua Tree National Park on a given day, against under 5% in June to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Calliopsis puellae sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Joshua Tree National Park, in our data
Joshua Tree National Park is the only park on Wallace's Line with enough records to rate Calliopsis puellae sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Hymenoptera
The closest relatives of the Calliopsis puellae that you can see in Joshua Tree National Park (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Messor pergandei (about 30%), California Harvester Ant (about 30%) and California Gall Wasp (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Calliopsis puellae is recorded against all the insects logged in Joshua Tree 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.
