Investigations using scanning electron microscopy (SEM) on the legs and mandibular structures of the carpenter ant, Camponotus compressus were observed. The ants were taken from the formicarium (an in-vitro ant culture) at the Entomology Research lab, Department of Zoology, Swami Ramanand Teerth Marathwada University, Nanded, Maharashtra; between March to October of 2022. Observation under SEM reveals that the mouth regions of the worker Camponotus compressus (Hymenoptera: Formicidae) carpenter ants are made for grabbing the prey and to feed upon it. The mandibles are large, shovel-like, cuticular, powerful, heavily sclerotized and unsegmented structures. In worker ants, the mandibles are made up of the Sensilla basiconica Bv, the Sensilla trichoidea Td-I and Td-II on the ventral side. Each mandible has three molar teeth and four incisor teeth in this species. The entire surface of the various leg sections showed that the coxa consists of two types of sensilla- sensilla trichoidea and fine hair like, trichomes, while the trochanter contains sensilla trichoidea, as seen under SEM structure. A smaller, spine-like tibial spur with fine cuticular bristles was visible on the mid and hind tibia. Senilla trichoidea, trichomes and comb-like bristles were found on the metatarsus of the foreleg, whereas macrosetae, sensilla trichoidea and trichomes are found on the metatarsus of the mid and hind legs. All tarsomeres have many bristles, setae and trichomes covering their whole surface, but the pretarsus of the foreleg has macrosetae. It is new insight observed on these species of ants using SEM.
