Dragonflies were the first flying insects that had existed around 300 million years ago. Now current dragonflies’ wingspans are only two to five inches, but fossil dragonflies had wingspans of up to two feet. They exist in every continent except Antarctica, because they live in moderate, hot, and terrestrial sites. They mostly start their life in water. There are more than 5,000 species are existing on this planet. They have belonged to the order of Odonata, which means “toothed one” in Greek. There are many more interesting facts about dragonflies.
