The loudest insects in the world, the Brood X species of Cicadas
emerged in 2021, after 17 years underground and the males
serenaded the females with mating choruses that can measure as
high as 90 decibels, about the same level as a shouted conversation.
After 17 years underground, when it's time to emerge, the
insects crawl up trees and tall plants shedding their nymphal skins.
After mating the females lay eggs in the branches of trees and
woody shrubs. After emerging cicadas live for about four to six weeks.
Once the nymphs hatch in six or seven weeks, they descend and dig
down underground to stay safe from predators and stay alive for the
next 17-year cycle.
