Meganeuropsis

Name means: “looking like it has large veins, after the big veins in its wings”
Eats: Other bugs and small animalsPrehistoric giantsPrehistoric6 legsNot a bug of today, but a prehistoric giant

Meganeuropsis looked like a giant dragonfly, and it is the biggest insect that has ever been found. It lived in North America about 285 million years ago, before the dinosaurs. From wing tip to wing tip it was wider than a big pizza.

This one died out a very long time ago. It is one of the most famous bugs of prehistoric times, so it gets a place in Bug Wiki too.
