Structural changes in the insect brain related to age and individual experience may underlie the behavioral plasticity that is particularly important in such social insects as bees. This study assessed the influence of age and rearing conditions (field vs laboratory) in mediating changes in the volume of mushroom bodies and antennal lobes in the brains of workers of the native stingless beeMelipona quadrifasciata anthidioides Lepeletier, a pollinator species with small colonies exhibiting high level of sociability and behavioral versatility.
