There are some patterns and similarities that emerge from watching a group of colonies in an apiary. Here are some from my out-apiary:
Hive E is very cross. I think that it may be low on stores. I tried to take the lid off to feed it. They went for me in full attack mode. Buzzng my head and my hands. My legs had at least a dozen bees attached, all trying to sting me.
The Limes are flowering in Headington. The Limes are flowering in Oxford. There are no bees on any of them.
I'm told that Limes only give nectar when the conditions are right. It has to have rained (which it hasn't recently) and it has to be humid (which it isn't ). These two presumably go together. The result is that Limes are only said to yield approximately every 7 years.
