Have a hive which was a rather late nuc and is now getting going quite well, and I have noticed a few dead drones on the ground in front of it.
I noticed what certainly seemed to be a worker bee (not bald) seeming to purposefully turn a dead drone over and crawl on top of it. Then it flew to the top of the hive (over 4 feet counting the 2 full depth hives plus the two chimney flue liners which it was setting on) The drones seem to have their abdomens intact so I don't think they died after mating.
I was surprised to learn that such a small bee could fly with that much weight, as the drone must have weighed almost twice what she did.
I noticed some bees dropping discs of wax off the board onto the ground, and some discs already on the ground.
I also noticed two white wormlike things about 1/2 inch long and maybe 1/8 or 3/32 thick lying on the landing board, seemingly dead. queen larvae maybe?
