Rare
Under 5% of wildlife watchers report an Urbane Digger Bee sighting in Saguaro National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 300th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October

Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Urbane Digger Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3

GBIF citizen-science records
It is estimated from how often the Urbane Digger Bee is recorded against all the insects logged in Saguaro 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.
