This photo shows two nesting tunnels (half of two nesting tunnels) containing two cocoons inside their mud cavities.
When nesting trays are not completely snapped togethr, a gap is present and lets air into the nesting tunnel. Consequently the mason bees muds over the gap forming a super – wall.
Hi Valerie, Thanks for sharing this photo with us and our friends. Yes this tiny little wasp is a parasitic wasp of mason bees (and other insects). You can see from the size of the cocoon in the background how tiny this critter really is! At the moment that this picture was taken, this wasp was listening for bee movement inside the cocoon ( it hears with its antennae). Only live bees are parasitized!! Great picture Valerie.
