What is low-altitude flight? Why do dragonflies fly low?
Dragonflies like wet environment, so they usually fly in ponds or rivers, and their larvae also need to develop in water.
Dragonflies not only prey on other insects, but also have the habit of adults eating each other among species. When they prey, they will catch their prey fiercely, and there are a lot of coarse hairs on their feet, which can help them catch their prey and make it impossible to escape. The mouth is also quite developed, it can bite prey, facilitate eating, and can eat up food equivalent to its own weight within 30 minutes.
Extended data
The research of dragonfly wings mainly focuses on mechanical principle and bionics. Dragonfly wings have two special structures: wing knots and wing moles, which make it an excellent flier in nature. In the study of mechanics, it is found that the dragonfly's wings will be affected by horizontal force, vertical force, moment, bending and movement when flapping and turning in the air, and it is found that the slow flight of dragonfly is very similar to that of an airplane.
The research methods of flight mechanics of dragonfly wings are also constantly improving, from tying with ropes to shooting with high-speed cameras and then observing in wind tunnels. More and more advanced methods make the study of dragonfly flight mechanics deeper.
