Note on glands present in meliponinae (Hymenoptera, Apidae) bees legs

Abstract

The present paper reports the presence of glandular structures in legs of some stingless bee species. The glands appear as: the epidermis transformation in a glandular epithelium as in basitarsus, an epithelial sac inside the segment as in the femur of queens or in the last tarsomere, as round glandular cells, scattered or forming groupments. The saculiform gland of femur is present only in queens, the other glands are present in males, queens and workers of the studied species, apparently without any type of polymorphism. This occurrence seems indicate that the function of these glands have not to do with the sociality or specific behavior of castes.
