Which insect has the longest lifespan?

Termite Queens – Termites have a similar colony structure to ants with a queen, reproductive males, and workers. Queens in a termite colony can lay more than 300,000 eggs in their lifetimes, and live for 25 to 50 years, making them the longest lived insect and explaining how they can cause so much damage to homes.

Some scientists believe that they live for 100 years.

Termite queens have the most important role in a termite colony, laying about 30,000 eggs, growing bigger and bigger as she does. Without her, there’d be no colony. With such an important role, it makes sense that she lives as long as she does — about 15 years. That’s about 500 times longer than males and 10 times longer than worker termites.
