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 will typically have from 10,000-50,000 or more bees in a hive. You may only see a small portion but the hives can be deeply hidden in walls, trees, chimneys, roofs, etc. Some bees are more aggressive than others and will swarm or sting if the hive is threatened or if someone gets too close.
