Q. Can you tell what is hanging out of the back of this Queen?

This newly mated queen has literally just returned to the colony after a successful mating flight as can be seen by the "mating mark" at the tip of her abdomen.
The process of mating for honeybees is quite frankly "violent"! The drones latch on to the back of the flying queen, having successfully mated, they are thrown off her back and at that point the penis is detached. What you are seeing in the picture is the remnants of the last successful drone to mate with this queen. The workers will assist in removing it and the queen should then settle down to start laying eggs and head up her colony.
