Cephalotes atratus is a species of arboreal ant in the genus Cephalotes, a genus characterized by its odd shaped head. These ants are known as gliding ants because of their ability to "parachute" by steering their fall if they lose their footing.

Males are up to 14 mm (0.55 in) and have black heads and thoraxes, and dark reddish-brown gasters and limbs. The workers are spiny and heavily armoured with powerful mandibles for chewing through wood.
This ant occurs in lowland tropical rainforests in South America where its range extends from Panama and Venezuela to Peru, Bolivia, Paraguay, Uruguay and northern Argentina. It is a common arboreal species and colonies are found in forested areas, parkland with isolated trees, and urban habitats.
This ant usually builds its nest in a hollow in a large live or dead tree. A small entrance may lead to a complex of tunnels and chambers, all excavated by the ants. From the nest the workers emerge... Wikipedia →

Possible
About 20% of wildlife watchers report a Common Giant Turtle Ant sighting in Santa Cruz de la Sierra on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 48 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Common Giant Turtle Ant in Santa Cruz de la Sierra on a given day, against under 5% in June and November–February, the lowest months. That is one of Santa Cruz de la Sierra's driest months, with about 40 mm of rain against 170 mm in January.

Of the 8 cities where we can rate Common Giant Turtle Ant sightings, Santa Cruz de la Sierra ranks 3rd at about 20%. The best odds are in Valencia (Venezuela, about 30%) and João Pessoa (Brazil, about 30%).
GBIF citizen-science records
It is estimated from how often the Common Giant Turtle Ant is recorded against all the insects logged in Santa Cruz de la Sierra (12 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.
