Summary
[edit]
| Description |
English: Dragonflies were some of the first winged insects to evolve, some 300 million years ago. Modern dragonflies have wingspans of only two to five inches, but fossil dragonflies have been found with wingspans of up to two feet. Arriving on the scene around 300 million years ago, dragonflies are one of the first insects to inhabit this planet. They've had a long time to perfect the art of flying, hunting and just being amazing. Here are seven facts that will change the way you look at these unique, ancient and incredibly varied insects. The area of an odonate's head is comprised primarily of its enormous compound eyes, which contain 30,000 facets, each bringing in information about the insect's surroundings. Dragonflies have a near-360-degree vision, with just one blind spot directly behind them. This extraordinary vision is one reason why they're able to keep a watch on a single insect within a swarm and go after it while avoiding mid-air collisions with other insects in the swarm. |
