Pheidole vistana
In 3 days ~10% in a week ~20%
Pheidole vistana is a species of big-headed ant native to Nevada, Arizona, California, Baja California, Baja California Sur, and Sonora. Its diet apparently consists of only insects, and many workers will cooperate to efficiently transport prey into the nest. It is a primarily nocturnal species that may rarely forage on overcast days. Large rings of sand often surround its nest entrances. The species is named after its type locality of Vista, California in San Diego County. Wikipedia →

Rare
Under 5% of wildlife watchers report a Vista Big-Headed Ant sighting in San Diego on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 437th most-seen of the 693 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Vista Big-Headed Ant in San Diego on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Vista Big-Headed Ant is recorded against all the insects logged in San Diego (14 verified sightings), 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.
