So it's a good thing honey bees are well-organized, task-oriented insects who stick together like family in colonies of several thousand workers per hive. And did you know that the honey bee is the only insect that produces food eaten by humans (unless, of course, cockroach milk takes off and becomes a thing)? So what the heck is bearding and why do honey bees do it? Honey bees are able to regulate the temperature of their hive throughout the year. In winter months, they raise the hive's temperature by huddling together and vibrating their wings to generate heat and keep warm.
