Queen bees have long abdomen like this, but it would be rare if ever to see a queen pollinating like that. Once they start laying eggs they are too heavy to fly. I would 90% guess it's a type of bee that I doing know, 10% it's a queen bee
Now that you comment on that I thought it was maybe perspective, but all other shots show that looooong abdomen as well. Fingers crossed it means lots of honey for the hive.
They're really difficult as they move a lot. The flash makes the difference to freeze the action. Being in focus is the hardest, so you have to take a lot of pictures and pray, lol. This is the only one in focus out of eight successive attempts. Insect macro photography is like that.
