Abstract - We investigated the morphology and ultrastructure of the cervical lobes of Apis mellifera drones with respect to age. The lobe epithelium decreases while the cuticle thickness increases as the drone gets older. Ultrastructural study revealed that the lobe has no secretory function but possibly acts as an inflatable bag during copulation.
