Hi

Does anyone know why the bees are ejecting larvae/half formed bees from the hive at this time of year - I have seen a dozen or so in the last few days.

Many thanks

Alan

They loose the brood to the cold, the brood is chilled. Happens if there is broodnest and bees start to cluster, leaving parts of the broodnest outside of the cluster.

My bees did so too but all evicted pupae had deformed wings. I see this as their hygienic behavior, removal of diseased brood. Deformed wings can be from varroa virus and chilled brood.

Quote:
When protein levels drop, nurse bees neglect young larvae, and preferentially feed those close to being capped. When protein levels drop lower, nurses cannibalize eggs and middle aged larvae. The protein in this cannibalized brood is recycled back into jelly. Nurses will also perform early capping of larvae—resulting in low body weight bees emerging later.

Conserving wild bees

Research suggests that bumble bee boxes have a very low success rate in actually attracting bees into them. We find that if you create an environment where first of all you can attract mice inside, such as a pile of stones, a drystone wall, paving slabs with intentionally made cavities underneath, this will increase the success rate.

Most bumble bee species need a dry space about the size a football, with a narrow entrance tunnel approximately 2cm in diameter and 20 cm long. Most species nest underground along the base of a linear feature such as a hedge or wall. Sites need to be sheltered and out of direct sunlight.

There is a spectacular display of wild bee hotels here
