Physical Characteristics Carpenter ants are a fairly large ant, ranging between 6 and 17 mm. This wide range is due to the dramatic differance in size between an adult queen and the small first generation workers.
Carpenter ants are black.
The scout then alerts other workers with a waggle motor display of its gaster. The workers then follow this trail to the food source. Although the motor display is usually preformed, it is not necessary. Reproduction Unlike many ant species, the workers never reproduce in a nest with a queen. Behavior The social system of carpenter ants consists of single queen nests, with infertile workers.
