The stingless bee, Trigona angulata fribrigi Schwartz, predominantly nested in radical cavities of at least 2 8 tree species in central Paraguay, but were more prone to predation by humans than nests located in trunk cavities. Colonies were randomly dispersed and occured at a density of 3.7 ± 4.3 colonies/ha. Multiple regression analysis revealed that temperature, time of day, and relative humidity explained a significant amount of seasonal colony foraging intensity (R2 = 0.66). Over seasons, colony foraging intensity and the number of flowering herbs and trees were canonically correlated with mean temperature, relative humidity, month and hours of available sunlight.
