Dorymyrmex bicolor is a species of ant in the Dolichoderinae subfamily, known as the bicolored pyramid ant due to the two-toned body color and the shape of their mounds. Dorymyrmex bicolor was recently known as Conomyrma bicolor but has been renamed to Dorymyrmex bicolor. It has a single petiole and a slit-like orifice which releases chemical compounds. This ant does not have the capability to sting. It is primarily found in arid desert regions in Central and South America and the southwestern United States. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bicolored Pyramid Ant is recorded against all the insects logged in Phoenix (6 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.
