Cicadas are large, stout insects. They have round bulging eyes on the corners of their heads, and short, bristly antennae. They have sucking mouthparts that attach at the base of their head.
Adults have four wings that they hold folded over their backs like the roof of a house. They also have special panels on the sides of their bodies called "tymbals." They vibrate these very fast to make loud sounds.
Young cicadas are called nymphs. They have no wings, and their front legs have thick claws for burrowing.
