The present study compare the size of the corpora pedunculata (mushroom bodies) of Exomalopsis aureopilosa a quasi-social specie and Apis mellifera a eusocial specie of bees. The aim was to correlate the developmental degree of such structures with the behavior complexity. The results show that the female specimens of both species have the corpora pedunculata with same relative size. However the area occupied by the neurones cellular bodies (glomeruli) is greater in the workers of A. mellifera. In other way in E. aureopilosa the total size of the corpora pedunculata is larger in females, but the glomeruli area is relatively larger in the male.

Key words: Hymenoptera, Apoidea, corpora pedunculata, glomeruli, castes, behavior
