The difference between summer and fall cicadas is:

Summer cicadas are most often found in the summer, while fall cicadas are usually found in the summer and fall.

Fall cicadas are also known as "mute cicadas" because the females can't call, while summer cicadas call from morning to night.

Summer cicadas are larger than fall cicadas.

Distribution range

Distributed in temperate and tropical regions, inhabiting deserts, grasslands and forests. In addition to the species of the genus Moth Cicada, which appears in midsummer every year, there are also periodic cicadas. The best known are the seventeen-year and thirteen-year cicadas, also known as prime number cicadas, which do not encounter the same predators they encountered in the previous generation because their life cycle is a prime number.

Periodic cicadas occur in large numbers at regular intervals in certain areas, when dozens to hundreds of dark-brown cicada larvae burrow out of the earth and feather together in a spectacular display. Some species are easier to identify by their song, behavior, and morphology.
