This time of year, the bees should be flying with purposeful intent, gathering pollen and looking for nectar. However, it’s also the time of year when we anticipate swarming behavior. This usually first occurs in healthy overwintered colonies a week or two prior to the start of the nectar flow (early deciduous leaf out). There will be some colonies that are ready early and some won’t be ready if ever. When you walk your bee yards notice the behavior at each hive. Just prior to swarming, there will be a lethargy on the landing board. I’ve noticed this several times over the years and only recently been able to understand why. Thanks to Jamie Ellis I now attribute this behavior to the soon to be swarming bees having engorged themselves with honey in anticipation for the coming swarm event. So, as a beekeeper this sign is your very last notice to take action if you wish to prevent losing 50 – 60% of your bees and possibly your honey crop from that colony. The choice is yours to take action then and there or risk seeing your bees take flight. Just look at those chubby bees!
