The dragon lice belong to the order Coleoptera and have strong flight ability, but when they see it, they are more in the water.
The reason why the dragon lice is good at living in the water is first of all due to the fact that it has a pair of flat and wide hind feet, and the edge of the hind feet is full of hairs, which can increase the contact area and friction with the water, resulting in a large thrust; secondly, the adult dragon lice are oval in shape, the body is streamlined, very smooth, and the resistance of swimming around in the water is small; third, the dragon lice have no cheeks, and it breathes in the water by the trachea of the abdomen, as well as the air carried under the elytra. When the dragon lice are active in the water, the air under the elytra is the "oxygen tank" it carries. If it runs out of air, it squeezes out the air under the elytra into a bubble, and the oxygen in the water can also enter the trachea through this bubble for the dragon lice to breathe. Therefore, dragon lice can dive underwater for a long time, even under the ice in winter, and can also lurk for a long time.
