Called the Demantidae, the Mulberry family lives on the surface of the water almost all its life, and with the help of adaptive traits such as water-repellent hairs and outstretched limbs under the body, it will not sink or be wet by water. Paddle on the surface of the water mainly relies on the movement of the middle and hind feet, and the forefoot is raised when moving, not used to row, and is mainly used to catch prey. Bugs feed on other insects, insect carcasses, or other animal debris that fall on the water.
The habitat includes still water surfaces such as lakes and ponds, as well as flowing water surfaces such as streams, and species that live on fast-flowing mountain streams often have a shortened abdomen or a few nodes constricted into the base. Groups such as the genus Murray live in the sea and float on the open ocean, and are one of the very few groups of insects that live normally at sea.
The body is small to large, oblong or oval. The back is mostly dark and dull, with no distinct spots. The ventral surface of the body is covered with a layer of extremely fine silvery-white short hairs, which are silvery-white velvety in appearance and have a water-repellent effect.
Head flat, monocular none. Antennae 4-segmented, distinctly extended. The beak is 4-segmented, stout, straight, but not close to the ventral surface of the head.
The anterior thoracic dorsal plate is extremely well developed and extends posteriorly, completely covering the midthoracic dorsal plate, and the appearance is not visible; This is especially true in the wingless type. There is no collar at the front end of the dorsal plate of the chest. The mesothoracic small shield is underdeveloped.
In wingless specimens, the dorsal plate of the posterior thorax is exposed, and the appearance is directly behind the dorsal plate of the prothorax. The forewings are homogeneous, more or less sheath-like, tapering toward the ends, but without a well-defined diaphragm. The paw division is not obvious, and the overlapping range of the left and right forewings is large when at rest, and no paw joint seam is formed.
Short wings and wingless are very common. The midfoot and hindfoot are very elongated and stretch out in all directions, and the hindfoot leg segments extend as far as 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 abdomen has a pronounced lateral border. Male holders degenerate in some species.
The female ovipositor is needle-shaped.

Dragonflies are insects that can walk on water. Hope my answer can help you, hope.

The one who watched the tea took the tea and ate it. Guo Shuban said: "Mrs. Jin has always been in the house, when did you come to Jiangnan?"
Although it was 'really fake', he also lost a few taels of silver. I was bored at home, because Mr. Yun Si Xun was an old friend of Beijing, so I came to Yangzhou to see him, and I recommended him on the box and sent a few hundred taels of silver.

Insects that live in water are called aquatic insects. Aquatic insects can be divided into two categories: one type of adult and larvae live in water; The other group is only aquatic larvae. There are not many species of adult worms that live in water.
In addition to mayflies and dragonflies, there are many groups of aquatic insects, such as wingers and turtles (Hemiptera), snakes and dragonflies, locusts (Coleoptera), stone silkworms (Trichooptera), butterflies (Lepidoptera), flies (Diptera) and many other groups. In particular, mayflies, dragonflies, wings, stone silkworms, etc., except for a few exceptions, all belong to the group of aquatic insects.
Water centipedes, dragon lice, red lady flowers, water axes, pine algae insects, field turtles, backstroke bugs, scorpion bugs, water striders, mud flies, fish lacewings, flat mud insects, scratching bugs, etc., are all aquatic insects.

1. Insects that walk on the surface of the water are called water striders.
2. The body of the water strider is slender and 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.
Some insects have a habit of living near water to have food and habitat.
<>Hello dear, I am happy to answer for you, the trapeze control strength is to find their own balance, the way is to open their arms to find the balance point, in order to make the body not sink into the water, the sole of the foot is not easy to find the balance point, only open the arms to adjust the control of the body contact with the water center of gravity, the center of gravity is stable to do bad control of the balance of the body in flight. The principle of being able to fly on the water uses a jet suspension aircraft. This device is to lift the operator to the surface of the water by spraying a high-pressure water column downward, so as to make some difficult movements. >>>More
The characteristic of insects is that the body is divided into three parts: head, thorax and abdomen, one pair of antennae, three pairs of feet, two pairs of wings, and compound eyes. These are the basic characteristics of insects.
The most industrious secret insect in "Insects", I think it should be bees, because bees carry out constant control work day and night. Well, people often use bees to describe people who are diligent and hardworking among human beings.
