Why do dragonflies fly low when they are ready to rain?

Most insects' wings are waterproof, and dragonflies are no exception, so that their wings will not get wet by humid air. Therefore, because the air is too humid, it is incorrect to say that dragonfly wings become heavier and cannot fly. Dragonflies may choose to fly low to prevent raindrops, hail and lightning from hurting themselves, and instinctively lower their flying height before it rains.

Usually, before it rains, the humidity in the air is quite high, and when insects fly, they often wet their wings when they encounter wet water vapor, so insects generally fly very low. This is a good time for dragonflies to catch their prey, so the low flying of dragonflies indicates that rain is coming.

Extended data:

Dragonflies like wet environment, so they usually fly in ponds or rivers, and their larvae (larvae) also need to develop in water. Adults often lay eggs by skimming water, preying on other aquatic organisms in the water, climbing out of the water before emergence, mating and laying eggs to complete their life history.

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.
