Tetragona clavipes was described by Johan Christian Fabricius in his Systema Piezatorum (1804).
In Brazil these bees have the common name borá, from the Tupi language. T. clavipes apparently is found in all the states of Brazil except Santa Catarina and Rio Grande do Sul, but is not common (Rodrigues et al., 2007).
Nests of T. clavipes are in tree cavities, and the colonies are "very crowded," and the inhabitants have "very aggressive habits" (Rodrigues et al., 2007).
Photo notes: This worker bee had its portrait made in Montsinéry, French Guiana.
