We have found 2-3 of these bees - dead outside our hive of Russian bees. We believe that this hive just requeened itself so it can't be bees newly hatched as we are just getting the eggs again - or we couldn't see them before (we have had capped larva throughout but the number kept getting smaller and now we are seeing lots of eggs. We decided to stay out of there for a few weeks now).
This was a hive that there was problems with robbing earlier but a robber screen solved that problem and we do not see fighting or dieing bees all over like before.
What kind of bee do you think this is?
