With luck
About 10% of wildlife watchers report a Pheidole xerophila sighting in Joshua Tree National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st 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.
March, July and September–December
In those months about 10% of wildlife watchers report a Pheidole xerophila in Joshua Tree National Park on a given day, against under 5% in January–February, April–June and August, the lowest months.

GBIF citizen-science records
It is estimated from how often the Pheidole xerophila is recorded against all the insects logged in Joshua Tree National Park (7 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.
