Residents of different regions of the United States have witnessed the appearance of huge clusters of cicadas. The highest activity is currently recorded in Georgia, Virginia and Maryland, but on the east coast, temperatures will soon rise, which means that there will be even more cicadas, they will appear in other states.
Periodic cicadas are underground for most of their life (as opposed to annual cycle cicadas). Experts assign a Roman numeral to the new generation, this year marks the invasion of generation X.
Entomologists note that the cicadas came to the surface for the first time in 17 years. The insects shed their exoskeleton, find a mate to breed with, and lay their eggs. Just before breeding, you can hear the "singing of cicadas" — the volume of these sounds can reach 100 decibels. According to entomologist John Cooley, this is an exceptional experience, because adult cicadas live only a few weeks.
