The basic function of the queen is to produce young. When the nest is first developed she lays her first batch of eggs and after 60 days the first brood of workers has been produced. Typically the first bath of workers that are born are small, due to the fact that they have only been feeding off of what the queen has stored in her body. Once they have grown to adults, the queen’s only job is to lay eggs. The workers job is to enlarge the nest and bring food to the queen and any larvae. Once the colony has reached a certain amount of workers (2,000 to 3,000), more reproductive males, females, and winged swarmers will be produced. In the summer months these swarmers, both male and female, leave the nest to mate. After they have mated the male dies and the female chews off her wings. She then finds a new location to create a nest, becomes the queen of that colony, and the process starts over.
