What insects can float on the surface of the water?

He is called water strider, also known as water horse, water fork, is an aquatic insect, and their fecundity is particularly strong, but it is not much harm to the human body.

The name of this bug is the water strider, which is a kind of bug that can jump on water, and it is very active and very scary.

This insect is a water strider, which looks more like a mosquito, but is larger, and it is most active in the summer.

This creature is called water strider, which is often seen in many areas and is also beneficial to humans.

Everything that is less dense than water can float on the surface of the water. In fact, needles can also float on the surface of water, although the density of needles is greater than that of water. Lay the needle flat and gently place it on the surface of the water to float.

This is because the weight of the needle is small, and the contact surface between the needle and the water surface is large, so the pressure on the water is small.

It is related to the density of the object, when the density is greater than the density of water, the object sinks, and vice versa, it floats up, the density of the first object is related, if the density is less than the water, it can float, the second pair of embroidery needles and the like, obviously the density is greater than the water, or it can float up, because of the surface tension of the water.

Foam, bamboo, ping pong balls, oil, some dry wood, and many more if you check the density table, objects smaller than water can float on the surface of the water, if it is made hollow, the density greater than the water may also float on the surface of the water.

The relevant information about buoyancy has 1: if. Yes, if you have a wooden board in your house, you can throw it into your bathtub, and the wooden board will float, indicating that the water is buoyant.

2: If you throw a hollow metal into the bathtub, it will also create the buoyancy of the water.

<> bugs that walk on the surface of the water are called water striders. The water strider has a slender body and is very light; The front feet are short and can be used to catch prey, and the middle and hind feet are elongated and have fine hairs with oily texture, which are waterproof; The body color is dark brown and the body length is about 22mm. It feeds on other insects, insect carcasses, or other animal debris that falls on the water, and inhabits still water surfaces such as lakes and ponds, as well as flowing water surfaces such as streams.

It is distributed in North China, Guangdong, Hainan, Guangxi, Zhejiang, Shandong and other places.

The insects that walk on the surface of the water are called water striders, commonly known as water spiders.

Water strider is an aquatic hemiptera insect, Hemiptera, and has the family Banded Bugs. Inhabits still water or slow streams. The body is slender and very light; The forefoot is short and can be used to catch prey; The middle and hind feet are very slender, and the long kai is covered with oily fine hairs, which have a water-repellent effect.

The body color is dark brown and the body length is about 22mm. Also able to live on land for a period of time.

Water striders have 3 pairs of legs, the forefoot is short, the middle and hind feet are very long, stretching out in all directions, and the hind leg segments extend more than the end of the abdomen. The forefoot is noticeably shorter. The tarsal segment is 2 segments, the end of the terminal segment is lobed into 2 lobes, and a pair of claws are born at the base of the fissure.

The back pair of legs can be used to control the direction of the slide, and the middle pair of legs are the driving legs, which are particularly long. The front pair of legs is shorter and is only used for hunting.

Water Strider Habits:

Water striders feed on the body fluids of small insects, dead fish or insects that fall into the water. Through the very sensitive organs of their legs, they can feel the struggle of insects falling into the water. By sliding a pair of legs in the middle of them they can move on the water, reaching speeds of meters and seconds, in addition they can do 30-40 centimeter high and far jumps.

When eating, the mouth is in a tube shape.

The habitat generally lives in still water, often gathering in groups on the surface of the water, and can be seen in parts of southern China for many years. Some species also live exclusively in running water. Most of the insects of the genus Sea Strider live on the coast, but there are also a few insects that live in the ocean and lay their eggs on floating objects.
