Seventeen-year cicada (magicicada septendecim) - the longest-lived insect. Seventeen-year cicada, order Homoptera.

A kind of cicada in North America lives in a cave for seventeen years before emerging.

They hibernate underground for 17 years before emerging, then attach themselves to branches, shed their skin, and then mate.

The male cicada dies after mating, and the female cicada also dies after laying eggs.

This is the happiest time for other insectivores. This is a rare feast. However, once the seventeen-year cicada climbs out of the ground, its life is very short. All the insectivores will swarm up to eat these seventeen-year cicadas.

If it weren't for their numerical advantage, this cicada would have become extinct long ago.

The vast majority of insects only have a life history of one year or less. The average cicada only has a life history of 3 to 9 years, although there is also a thirteen-year cicada.

This cicada lives underground for 17 years, giving it the title of longest-lived in the insect world.
