2021年7月22日 · For dragonflies, the main reason they fly is to go out hunting and catch insects on the wing. Aside from hunting, dragonflies use flight to attract a mate. Male dragonflies will fight each other in order to claim a territory in a bid to attract the most females.

A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world.

Dragonflies are incredible flying machines! They are the strongest flyers in the insect world. Compared to most other insects, dragonflies can fly further and higher than other insects.

2014年11月25日 · By tracking the body and wing orientations using high-speed video recording of this rapid roll in high resolutions, the team uncovered how dragonflies were altering the aerodynamics on their...

At a glance, you can see that a dragonfly has a prominent head, an elongated body, and two pairs of slender wings extending to each side. As it takes off, the wings appear as a blur. In air, the dragonfly dances in unpredictable steps, hovering briefly then quickly moving to a new location.

2018年7月2日 · Dragonflies are acrobats of the sky. They can fly upside down, turn 360° on a dime, and fly more than 55 kilometers per hour. They can even fly backward with as much skill as they fly forward. Now, researchers have figured out how they execute this tricky talent.

2025年1月13日 · ATLANTA— Among the most agile of flying creatures, dragonflies have evolved to perform quick aerial maneuvers—akin to planes in a dogfight—both to attract mates and to catch prey midair. Now, researchers have documented and explained a unique stunt the insects perform so quickly most people never see it.
