When the dragonfly flies low, does it indicate that it is going to rain?

Odonata The members of this order are mostly large and medium-sized insects, with large heads and flexible rotation, two pairs of wings with transparent membranaceous membranes, many transverse veins on the wings, and often 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, which can only indicate that the air pressure is low, and sometimes it does not rain.

Before the rain, the humidity of the air is high, and the wings of the dragonfly become soft and cannot fly high.

Because before the rain, the humidity in the air increases, and small water droplets attach to the dragonfly's wings, so they can only fly low.

Dragonfly: If you fly up and down in the air, there will be heavy rain in about 2 hours. "Dragonflies are circling in thousands of ways, and the rain will come soon. "Dragonflies fly low and go out with a raincoat. "Although dragonflies fly low in the wind or rain, sometimes they don't have to.

Oh, yes... I think it's because of the air pressure or something.

Question 1: Why do dragonflies and swallows rain when they fly low? Usually before rain, the humidity in the air is quite high, and when dragonflies fly, they tend to wet their wings when they encounter damp moisture; In this way, no matter how strong the dragonfly's ability to fly is, due to the heavier wet body, it is difficult to fly at a higher altitude as usual, and can only fly at a low altitude.

Question 2: Why do dragonflies fly low when they are ready to rain When it is about to rain, the humidity of the air is high, so that the wings of the insects that the dragonflies want to hunt are stained with water, and the insects cannot fly high because of the water on their wings, and the dragonflies also take the opportunity to hunt. So when it rains, dragonflies should fly low. Hope it helps.

Question 3: Why do dragonfly swallows fly low before it rains? It must be fast, if there are no insects to eat, the air humidity is high, many small flying insects will "want to fly but not fly high", and swallows will fly low if they want to eat insects.

Without insects, swallows basically do not fly low, first: the swallow's feet can't support its own weight, it flies all the time. But it's all high-flying.

Thank you. Because when it rains, there will be a lot of moisture in the air, and the wings of some small flying insects are stained with water, and they cannot fly high, so swallows can only fly low in order to eat more flying insects. If you don't happen to be too small when browsing, press F5 to refresh it.

Question 4: Why does it have to be a rainy day when the dragonfly flies low Because the air will be humid before it rains, and the dragonfly's wings are very thin, the moisture in the air will attach to the dragonfly's wings. It puts a certain amount of pressure on the dragonfly, so it can't fly high

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.

The reason why dragonflies fly so low before it rains is that dragonflies have wings that are web-filled and leaf-shaped, unlike feathered animals that can withstand large air pressure. When it is about to rain or cloudy, the climate is relatively humid, the humidity in the air is very high, the composition of 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.
