<i>Camponotus floridanus</i> Colony (IMAGE) University of California - Riverside Caption Photo shows Florida carpenter ants castes, major workers and minor workers, taking care of the brood. These are one kind of ants the researchers studied. The cuticle of the workers and the queen is enriched with specific hydrocarbons, many of which act as pheromones and are sensed by others in the colony. Credit Juergen Leibig.
