HYG - 12 Carpenter ants are social insects that live in colonies made up of several different forms called castes. Each caste has its own specific function necessary for the success of the colony.
Pupae are legless, white and grub-like.
The carpenter ant is one of the largest ants common to the United States. Unlike termites, all carpenter ants have constricted waists. Workers are not winged, but reproductives are. However, colder weather may lengthen this period to as long as 10 months. The few workers to emerge from the first brood pupae are small, but they energetically assume the duties of the colony.
