Brachygastra lecheguana (Latreille, 1824), formerly known as Nectarina lecheguana, is a species of dark paper wasp found across tropical to subtropical America. It nests in underbrush in grassland-type environments, and species of the genus Brachygastra store honey, a trait characteristic of the genus.
Common names include marimbondo-do-campo, marimbondo-do-pasto, marimbondo-exu, marimbondo-de-pote, marimbondo-de-purrão, and avispa-de-pote, among others depending on the location. It is called tu in the Kwaza language of Rondônia, Brazil.
B. lecheguana belongs to the Epiponini tribe of Polistinae wasps, sometimes referred to as Polybiinae wasps. It is a Neotropical social wasp species that falls under the genus Brachygastra. Brachygastra wasps are identified, as noted in Andena and Carpenter (2012), by an anatomical projection over their posterior. The scutellum, metanotum, and propodeum, three of the hymenopteran back structures, combined form a flat, vertical surface in the middle of the body (mesosoma).
B. lecheguana is very closely related to B. mellifica and B. borellii, and indeed some authors suggest that B. lecheguana and B. mellifica can only be differentiated... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brachygastra lecheguana is recorded against all the insects logged in Buenos Aires (230 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.
