Hello. First year beekeeper here. I have a hive of Italian bees (I think - that's what I was told) but I'm seeing a different bee mixed in with mine. While mine are more yellow stripped and blunt shaped this bee is darker and it's tale end is black. It's also shaped almost wasp-like with a very narrow abdomen. They haven't been aggressive and ignore me around the feeder. My honeybees will check them out but they don't bother each other. You can see both bees in the attached picture. Mine is the yellowish one at the top and the other bee is the dark one at the bottom. Can someone tell me what kind of bee that is?
