A Comparative Study of Relational Learning Capacity in Honeybees (Apis mellifera) and Stingless Bees (Melipona rufiventris)
It has long been known that bees have an impressive capacity to learn and discriminate colors, shapes, patterns and odors [2][6]. These learning abilities have been investigated mostly in the common honeybee Apis mellifera, but also in bumblebees [7][12], and even new-world stingless bees, such as Melipona rufiventris and M. quadrifasciata [13][17].
