Why do dragonflies fly so low on rainy days

On rainy days, the humidity in the air is high, and many insects have difficulty flying high after their wings are damp, so dragonflies also follow to hunt small insects at low altitudes.

By the way: dragonflies are very capable of flying and have large individuals, and the usual water vapor does not affect their flight.

Dragonflies (odonata).

Most of the members of this order are large and medium-sized insects, with large heads and flexible rotation, two pairs of wings with transparent membranaceous texture, many transverse veins on the wings, and wing nevi on the front edge of the wings near the apex of the wings.

It is distributed all over the world, especially in the tropics. About 5,000 species are known, and about 350 species and subspecies have been recorded in China.

Many dragonflies do not have ovipositors. They hover above ponds or fly back and forth along streams, scattering their eggs into the water as they fly; Some species fly close to the surface of the water and lay their eggs in the water by "spotting" them with their tails.

Adults catch insects of the right size during flight and feed on them. Dragonflies mostly fly over open areas. Insects of the Fly family often come out at dusk to hunt mosquitoes, small moths, leafhoppers, etc., and are important beneficial insects.

When the weather turns bad, insects mostly fly on the ground.

This phenomenon can only indicate that the air pressure is low, and sometimes it does not rain.

It is possible that there are many dragonflies in the low altitude of an area, and it is more likely to be a sign of impending rain.

Usually before the rain, the humidity in the air is quite high, and when the dragonfly flies, it often wets its wings when it encounters humid moisture, which is a good time for the dragonfly to catch its prey, despite the dragonfly's ability to fly.

Due to the heavier wet body, it is difficult to fly at a higher altitude as usual, and can only fly at low altitude, so the dragonfly flies low.

There is a proverb that says, "Dragonflies fly low, and it rains when it doesn't rain." "Before the rain, the air pressure is low, insects mostly float at low altitudes, and dragonflies often fly two or three meters above the ground in order to feed, which is a sign of impending wind and rain.

It is the wings of dragonflies that are leaf-shaped, unlike feathered animals that can withstand large air pressure. When it rains or is cloudy, the climate is relatively humid, the humidity in the air is very high, the composition of the dragonfly wings is keratinized protein, when the dragonfly flies, when it encounters humid water vapor, it often wets the wings, and the dragonfly does not fly high due to the weight.

Therefore, as soon as experienced farmers see dragonflies flying low, they know that it is going to rain, and make early arrangements for their agricultural production to prevent the loss of crops caused by rain. It seems that if you observe carefully in life, there is learning everywhere.

Dragonflies fly low for several reasons:

1. Foreshadowing rain, which is an important way for the farmer to judge the weather. Because when it rains, the humidity in the air is heavier, and the humid air wets the dragonfly's wings, which increases the load on the dragonfly and causes it to fly at low altitude.

2. Dragonflies fly low to catch food. The humidity of the air causes some insects to fly relatively low, and dragonflies fly low in order to hunt their prey.

3. There is also a situation where dragonflies will also fly low over the pond when they lay eggs. The aim is to sow their eggs in the pond water and give birth to the next generation.

The humidity is lower and the body is heavier.

According to the query question bank test questions: Why do dragonflies fly low before rain? The answer is parsed as:

Usually before the rain, the humidity in the air is quite high, and when the dragonfly flies flying, when it encounters humid moisture, it tends to wet its wings, so it flies low; In addition, it is a good time for dragonflies to catch hunting hand animals, and dragonflies will be seen flying low. So the dragonfly may have chosen to fly low to prevent raindrops, hail, and lightning from hurting itself, and instinctively lowered its flight altitude before it rained.

The fly is an insect and it is an invertebrate. Dragonfly is a common name for insects of the insectage order Dragonfly, which belongs to the invertebrate group. Dragonflies are larger, with long, narrow wings and well-defined reticular veins, in addition, dragonflies have a pair of compound eyes and clear vision.

Rain can have an effect on their wings, making it difficult for them to maintain the stability of their flight.

Dragonflies fly low and quickly when it rains because the rain will affect their wings, making it difficult for them to maintain the stability of their flight, so they will choose to fly closer to the ground to ensure safety.

Dragonflies are a common insect and one of the important links in the ecosystem. They can help control the population of some pests and are also food for other animals**. Dragonflies are very agile when flying, and are able to quickly change direction, up and down, thanks to their unique wing structure.
