When we think of “swarms”, bees are often at the top of the list. They are colonial in nature, and when threatened, they will attack in great numbers. But bees are among the most beneficial species on this list, pollinating flowers and producing honey. As humans, we rely on bees tremendously.
Nevertheless, bees can be quite dangerous, especially for those who are allergic to their painful stings. In New York City, urban beekeepers are raising millions of bees, and inevitably, amateur beekeepers are allowing some of them to escape. This has caused a multitude of problems, where 10,000 or more bees have swarmed onto stops signs, SUVs, and other objects around the city.
