(Length: 1/2″) These “hairy” bees have yellow and dark brown coloring and thick bodies. They are not aggressive and will leave people alone if not provoked, but they are defensive and will attack anything that threatens the colony or individual. They forage on pollen and nectar from which they produce honey to feed the colony. Honeybees usually nest inside cavities in trees, but will also nest in gaps beneath rock formations. Their stings can be painful and can cause a serious reaction (anaphylactic shock) to allergic individuals.
