Flying insects room usually annoying. Mosquitoes bite you, leaving itchy red welts. Bees and wasps sting. Flies are just disgusting. Yet there’s something magical about dragonflies.

You are watching: Why do dragonflies have two sets of wings

1 ) Dragonflies were several of the very first winged insects to evolve, some 300 million year ago. Modern dragonflies have actually wingspans of just two to five inches, but fossil dragonflies have actually been discovered with wingspans of up to two feet.

2 ) Some researchers theorize that high oxygen levels throughout the Paleozoic era permitted dragonflies to thrive to monster size.

3 ) there are an ext than 5,000 known species of dragonflies, every one of which (along v damselflies) belong to the stimulate Odonata, which method “toothed one” in Greek and refers to the dragonfly’s serrated teeth.

4 ) In your larval stage, which can last up to two years, dragonflies room aquatic and eat just about anything—tadpoles, mosquitoes, fish, various other insect larvae and even every other.

5 ) in ~ the end of the larval stage, the dragonfly crawls the end of the water, climate its exoskeleton crack open and also releases the insect’s abdomen, which had actually been pack in prefer a telescope. Its four wings come out, and also they dry and also harden over the next several hrs to days.

6 ) Dragonflies are expert fliers. They can fly straight up and down, hover like a helicopter and even friend mid-air. If they can not fly, they’ll starve because they just eat food they record while flying.

7 ) Dragonflies catch their insect food by grabbing it through their feet. Castle so reliable in their searching that, in one Harvard university study, the dragonflies caught 90 come 95 percent the the prey released right into their enclosure.

8 ) The trip of the dragonfly is so one-of-a-kind that it has actually inspired designers who dream of making robots that fly favor dragonflies.

9 ) part adult dragonflies live for just a few weeks while rather live approximately a year.

10 ) Nearly all of the dragonfly’s head is eye, for this reason they have incredible vision the encompasses almost every angle other than right behind them.

11 ) Dragonflies, which eat insects together adults, room a good control ~ above the mosquito population. A single dragonfly deserve to eat 30 to thousands of mosquitoes per day.

12 ) hundreds of dragonflies of different species will gather in swarms, either because that feeding or migration. Tiny is known around this behavior, yet the Dragonfly Swarm project is collecting reports ~ above swarms to far better understand the behavior. (Report a swarm here.)

13 ) Scientists have tracked migratory dragonflies by attaching tiny transmitters come wings through a combination of eyelash adhesive and also superglue. They discovered that environment-friendly darners from new Jersey traveled only every 3rd day and an median of 7.5 miles every day (though one dragonfly traveled 100 mile in a solitary day).

14 ) A dragonfly dubbed the globe skinner has the longest migrate of any kind of insect—11,000 miles back and forth across the Indian Ocean.
