Aren't all the worker bees female?

Maybe she'll run out of steam later and let the poor hummers have a turn.

Might chase the bee away.

got a little jar and will set them free in the back yard......they both are just harassing the hummers. I love my hummers. They have names, gazer, twinkle toes, hump back and bubble nose. That's four that we know of....or that they have the same mannerisms at the feeder so we've named them. Going to try and catch the bees right now......I'll let you know if I succeed.

Good luck.

At any time during the day there are several hundred forager workers out of the hive.

I suggest you check two things: Any drippings or spillage from the feeder. If there is any, that's what is attracting them. Second, the distance between the opening(s) and the sugar water. Bees' tongues are very short. If they can't reach the liquid, they give up.
