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.
Swarming honey bees do not have a nest to defend and 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 hanging in a tree, shrub or house you do not need to do anything.
