Yes, I know that for sure, but I was more-so talking about the behavior of our local, feral bees here. he's a good 20 miles away from me, so I know that my bees are in their own little eco-system. I just wish I had a queen I could use to verify if they have one, but if they do, I'd still be very upset with why they aren't building.. We will have temps in the 80s to low 90s through the rest of this week, so if that doesn't give them any warmth, I don't know what will. I figure at this point, I'll just keep the feeder on, let them be, and if they fail, then I'll probably have to try again, or wait until next spring.
