Rare
Under 5% of wildlife watchers report a Pheidole xerophila sighting in Saguaro National Park on a given day, based on 6 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.
September
In that month about 10% of wildlife watchers report a Pheidole xerophila in Saguaro National Park on a given day, against under 5% in October to August, the lowest months. That is one of Saguaro National Park's wettest months, with about 50 mm of rain against almost none in May.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Pheidole xerophila sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Pheidole xerophila sightings, Saguaro National Park ranks 2nd at under 5%. The best odds are in Joshua Tree National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Pheidole xerophila is recorded against all the insects logged in Saguaro National Park (6 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.
