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 bees are a yellow-orange color. During the spring, honey bee colonies may swarm. Swarming is the process of honey bee colony reproduction and involves the splitting of a colony where 30-50% of the bees leave the hive with the old queen. The swarm flies to a temporary site for a day or two before a new permanent nest site is chosen. These swarms often alarm people, but bees in this state are very docile because they donât yet have a nest to defend. Honey bees prefer to build a nest in a sheltered location such as a hollow tree, wall, or attic and seek out such locations.
