Trigona fulviventris, known by the common names "culo-de-vaca," "culo-de-señora," "mu'ul-kab," "culo-de-buey," and "culo-de-vieja," is a species of stingless bee found in neotropical regions of Central and South America.[1] It is one of the largest and most widespread bees of its genus.[2] They exhibit complex foraging behaviors by integrating spatio-temporal learning and flower scents. T. fulviventris has traditionally been observed to abstain from aggressive behavior with other species; however, more recent analyses have shown that T. fulviventris emit pheromones that act as attack signals particularly when related individuals are captured by predators.[3]
