I have noticed the last couple pf days a few bees running around the landing board flapping their wings but can't fly. They eventually fall to the ground and die. They have also been carrying out a few dead bees. The abdomens of the effected ones are curled under pointing down.
Michael, They are smaller and fuzzy. The original package was all this type of bee. As the new queens brood have hatched they are larger and darker. Some have a black tip on the abdomen. I am not seeing as much of it but still some, even the darker bigger bees.
I can't see them so well in the picture, but look carefully at their wings and see if they are normal or crumpled or "K" winged (the two wings on one side separated instead of attached together as a unit).
Could be mites, feeding on the pupae and doing enough damage to distort the bee as it develops. I saw one bee like that at my big hive, haven't seen any since. A mite count could be in order, although if the hive seems to be doing well it's not critical to do it now.
