The venom gland in social wasps is both the source of their venom and of their alarm pheromones. As is the case in most ante, the venom reservoir contains a secretory region within, known as the convoluted gland. In contrast with ants (venom gland with one single free tubule), the venom gland in wasps contains two free tubules. Our new observations deal with the association of the so-called << free tubules >> with fat cells. The association of these tubules and the fat body is already very obvious during the pupal stage.
