I've noticed a bunch of black bees in my hives (starting about 2 weeks ago). I'venever seen black bees in my hives before. Could they be robbers? Check out this picture:
They seem to be in the entrance feeder mostly when I pull off the jar. I have robber screens ready to put on and a frame feeder to start using but I haven't put them on yet. I hope I'm not too late.
Also, just an interesting observation........saw a HUGE bee ..... and I mean HUGE... flying around the two hives earlier today. I went in the house to get a tennis racket to smack it away and when I came back it was gone. It was yellow and black and was at least a 1.5 inches long and very fat. Not a carpenter bee because I've had those for years. It was something else and very scarry looking.
Thanks in advance for your advice/comments!
