What is the name of the spider like bug that floats on the water?

It seems to be called a water fly in the image, but when I looked it up, it was called a water strider, and there were many on the surface of the still water such as a pond, and it would prey on those insects that fell into the water, and sometimes it would fly. The online information is as follows:

Water Strider Water strider is an aquatic hemiptera insect, Hemiptera, in the family Water Strider.

Hanyu Pinyin: shuǐ miǎn

Family: Water Striders.

Scientific name: aquarlus elongatus

Habitat: Inhabits still water or slow streams.

Exterior features: slender body, very light; The forefoot is short and can be used to catch prey; The middle and hind feet are elongated and have fine hairs with an oily texture, which is waterproof. The body color is dark brown and the body length is about 22mm.

It usually lives in groups and can be seen in some parts of southern China for many years. When the eggs are hatched, the nymphs sink to the bottom of the water first, and soon float to the surface, and with the activities of other individuals, they move quickly on the surface of the water, and the female dies soon after laying eggs.

The water strider is a small aquatic insect commonly found in lakes, ponds, paddy fields and wetlands, measuring about 1 cm in length and paddling across the water. It has 6 slender legs and cilia on its feet.

A medium-sized water strider weighs about 30 milligrams, which is lighter than water, so it will not sink into the water when it walks on the water.

In addition, there are rows of non-watery hairs growing on the joints of the foot of the water strider, so the part of the water that comes into contact with the foot will be concave, but the toe of the foot will not break through the surface tension. The water strider has three pairs of legs, and the division of labor between the three pairs of legs is also very clear, the forefoot is used to hunt, the middle foot is used to divide and jump, and the hindfoot is used to glide on the surface of the water, so that it can move freely on the water.

However, if you add a little neutral detergent to the water, it will weaken the surface tension of the water, at this time, the hair on the feet of the water strider walking on the surface of the water is wet, and the foot breaks through the surface tension and penetrates into the water, the water strider will sink into the water, and when the water strider sinks, due to the effect of surface tension, the water strider will no longer float.

The small aquatic insect water strider is known as the "skater in the pond" because it not only glides on the water, but also jumps and plays gracefully on the surface like an ice skater. Its brilliance is that it neither cuts through the water nor soaks its own legs. Water striders are not only harmless to humans, but can hunt and kill insects or become bait for fish.

When the fifth instar nymph of the water strider turns into an adult after molting, it is often seen that they have mating. The male will crawl above the female for about thirty minutes. When the adult of the water strider has copulate, the female's main job is to lay eggs. It prefers to lay eggs on small, thin stalks of aquatic plants.

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.

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. The hairs on the tarsal joints allow them to move very quickly on the surface of the water with the help of surface tension without sinking.

Floating on the surface of the water is a tiny creature that looks like a tiny bug, and it is called a "floating fireflyer". I usually see daffodils, lotus ponds, glasses and other small things floating in the water, and most of them are them. They are one of the few species of insects that are able to live in water.

This small bug is named by the translucent, light-transparent gastropod insect larvae that prey on small aquatic organisms such as plankton, insect larvae, small fish eggs, etc. The main task of the adult worm is to give birth and carry out the continuation of the population, and the adult life period is only a few days, only appearing at night, and at the same time has the characteristics of emitting weak, flickering light.

The floating firefly also indirectly maintains the ecological balance through the intervention of the Minqiu ecosystem. Because in this insect ecosystem, there are many prey in the chain, and in the process of these creatures attacking and replenishing food, the natural balance gradually emerges. So in modern society, we need to protect water resources and protect such insects.
