Camponotus atriceps
In 3 days ~20% in a week ~30%
Camponotus atriceps, previously referred to as C. abdominalis, is a species of carpenter ant, endemic to the Americas. In the Amazon region, C. atriceps has been seen attacking colonies of stingless bees of the genus Melipona, especially M. flavolineata and M. fasciculata. It destroys hives and eats brood when food is low. Field research at Embrapa Amazônia Oriental in Brazil discovered that ants can be attracted to empty hive "trap boxes," offering an efficient non-chemical alternative for safeguarding managed bee colonies. Utilization of trap boxes in communal shelters of stingless bee colonies can serve as a non-chemical method for controlling tracuá carpenter ants (C. atriceps). Wikipedia →

GBIF citizen-science records
It is estimated from how often the Tropical Carpenter Ant is recorded against all the insects logged in Cumbres de Monterrey National Park (17 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.
