The adult Dog Day Cicada is dark brown or black. A gold mark on the thorax is shaped like two 'V's. A green band at the back of the head stretches into its large wings. The eyes stick out of the sides of the head. Adults are not known to eat. Instead, they focus their energy on reproducing during their short lifespan. It breeds, lays eggs on branches in trees, and then it dies. Larvae hatch from the eggs and fall to the ground, burrowing down into the earth to mature. They may drink fluids from tree roots.
