The term 'social bugs' can refer to ants, which are four-letter insects that live in colonies and work together to build complex structures. Ants are known for their social behavior, as they communicate with each other through chemical signals and work together to find food and protect their nests. They also have a division of labor, with different types of ants performing different tasks. Ants are found all over the world and can be beneficial to humans, as they help to control pests and aerate soil.
