Is a dragonfly a fly?
Is a dragonfly a fly?

No. Flies are insects with two wings. However, both flies and dragonflies are insects, meaning that they have six legs and three body parts: a head, a thorax, and an abdomen.
The name comes from their fierce jaws, which they use to catch flies (among other winged insects).
Dragonflies are ancient insects. They were around before the dinosaurs! Ancient dragonflies may have been considerably larger than those we see today.
This dragonfly lived 300 million years ago and had a wingspan of eight inches. The largest known dragonfly had a wingspan of 24 inches (two feet). Today, the largest dragonfly is found in South America and has a wingspan of slightly over seven inches. Other than being smaller, modern-day dragonflies do not look very different from their ancestors.
