1 The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).  The disease now affects men and women almost equally, due in part to increased tobacco use among women in high-income countries.
Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
Honey bee swarms are not highly dangerous under most circumstances. Swarming honey bees feed prior to swarming, reducing their ability to sting. Further, bees away from the vicinity of their nest (offspring and food stores) are less defensive and are unlikely to sting unless provoked. In most situations when a honey bee swarm is found on a tree, shrub or house you do not need to do anything.
