We have three beehives on our farm, and I am the one that takes care of them. Visiting the hives and observing them around the hives tells me they are still active. Watching the little bees right outside the hive is fascinating. When it is too hot for all the bees to go inside, some of them wait on the side of the hive. They need to keep the temperature at about 96 degrees.
There are also the workers that are going along the outside to add propolis to the upper super. Even though our winters are not as cold as winters back east, the mornings get cooler in the winter months. I have read that the bee’s know that it is going to rain well before we do because the ice crystals in the air. I did notice the other day before it rained, there were no bees to be found on the roses.
