Rare
Under 5% of wildlife watchers report an Essig's Carpenter Ant sighting in Sacramento on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 350th most-seen of the 386 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.
March
In that month about 10% of wildlife watchers report an Essig's Carpenter Ant in Sacramento on a given day, against under 5% in April to February, the lowest months. That is one of Sacramento's wettest months, with about 90 mm of rain against almost none in July.
Only Sacramento, in our data
Sacramento is the only city on Wallace's Line with enough records to rate Essig's Carpenter Ant sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Formicidae
The closest relatives of the Essig's Carpenter Ant that you can see in Sacramento (family Formicidae, Ants) are American Winter Ant (about 10%), Western Velvety Tree Ant (about 10%) and Argentine Ant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Essig's Carpenter Ant is recorded against all the insects logged in Sacramento (5 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.
