What are the characteristics and habits of water beetles?

Water beetles, also known as water turtle insects, look like dragon lice.

It lives in the same water ecological environment as dragon lice, the body is streamlined, the dorsal and ventral surface is arched, but the dorsal body is more convex than that of dragon lice, the body color is darker (almost black) than dragon lice, the ventral surface is flat, most species have a thick and straight needle on the ventral surface of the chest, which is attached to the ventral surface of the chest and stretches backwards (dragon lice have no needle puncture), and the lower jaw is long, equal or longer than the antennae. From these points it is possible to distinguish them. This crustacea.

It is good at crawling on objects in the water, and often spins around on the surface of the water when it swims towards the surface. Water turtle insects belong to elytra.

The order is about 2,000 species known in the world. The antennae of the terrapilla are 6-9 segments, the end of the 3-4 segments is slightly expanded, and there is a shallow groove on one side of the antennae, which is covered by water-repellent hairs, thus forming a tube, which swims to the surface of the water when breathing, leaving the head exposed, and air enters through the duct of the antennae, and is stored on the short hairs that are dense on the ventral surface and will not be wet by water. At this point, a large layer of air can form on the hairs, and the ventral surface becomes silvery-white due to dense blisters.

Underwater by the movement of the elytra and the ventral plates, the air from the bubbles is drawn into the air storage chamber and trachea under the elytra. Its ventilation in the water is also carried out by means of antennae. Adults are generally herbivorous.

The larvae are carnivorous or carnivorous, preying on animals such as tadpoles and small fish, and some species have been reported to harm rice.

The water beetle, or water turtle insect, is an insect that lives in water. They are usually flattened in shape and generally have a body length of between 1-3 cm, with some varieties reaching more than 5 cm. Water beetles often have many bumps and depressions on their body surface, and these structures help swim and breathe in the water.

Water beetles belong to the order Coleoptera, the family of water turtle insects, also known as the family of odontidae, and there are about 2,000 known species in the world. They are good at crawling on objects in the water, and when swimming towards the surface, they often spin around on the surface of the water. Water beetles breathe through breathing ducts on the surface of their bodies, drawing oxygen into their bodies while expelling carbon dioxide from their bodies.

Water beetles live mainly in water, they may live in still water or flowing water, and most species live in ponds, ditches, lakes and paddy fields. The larvae of the water beetle usually live in the water, while the adults live near the water.

In summary, the water beetle is an insect that lives in water, with unique physical characteristics and breathing patterns, they may live in still water or running water, and adults usually live near water.

The characteristics of the beetle are:The forewings become hard wing sheaths, which no longer have the function of flight, but only protect the hindwings and the body. To fly, first raise the wing sheath, then spread the thin hind wings and fly into the air.

The color of the wing sheath varies, some are golden, some are striped like tiger stripes, some are spotted like leopard skin, and some are variegated patterns.

Characteristics of life:Some larvae are free-roaming, while others often hide in hidden places. Most of the larvae pupate in the soil or in hidden places, and do not form cocoons, although some species will form cocoons to protect the pupae.

From larvae to adults, it takes only a week, and some take 20 years. According to the feeding habits, antennae shape, wing veins, etc., beetles can be divided into three categories: carnivorous, polyphagous, and snouting.

Beetle head features.

Compound eyes are usually well developed, round, oval, or kidney-shaped, some degenerate or disappear, and rarely have a single eye.

The upper lip is well developed, some are hidden under the base of the lip or disappear, the upper jaw is more developed, and some species are very powerful, almost the same length as the body; The lower collar is prominent, and the lower jaw of the carnivorous suborder is divided into outer lobes and inner lobes, the outer lobes are divided into 2 segments and are whiskered, and the inner lobes are developed and leaf-shaped.

Beetles generally live in damp beetles generally live in damp.

The larvae are moistened with fermented wood chips, and the wood chips and bark are placed on the inside of the adult box, which also need to be moisturized.

Eating a wide range of foods: Beetles can eat different kinds of food such as plants, carrion, and even other insects.

Strong reproductive ability: beetles can breed their offspring by laying eggs or directly by laying eggs, and can generally lay many eggs at a time.

Good at digging and hiding: Some beetles will dig burrows or dig tunnels and hide themselves and their food inside.

Prefer light: Some beetles prefer to be active in well-lit places, such as glow-in-the-dark beetles, fireflies, etc.

In conclusion, beetles have a variety of habits and adaptability, making them very interesting creatures.

The beetle is one of the most common insects, their habits are mainly to feed on leaves and wood, some of the beetles will haunt in hot weather, the habit of the beetles is that they will continue to reproduce, under the right conditions, the number of beetles can increase quickly, because of its strong fecundity, so their numbers in nature are also very considerable.

1. Beetle habit: only lay an egg, and then roll it from the dung heap to a cool place, the ancient Egyptians compared this habit of the beetle to God rolling the sun in the sky, giving life to the earth. The beetle became the mascot of life and reproduction.

2. Beetle or beetle is the common name for Coleopteran insects.

3. In the cultural system of ancient Egypt, it was revered as the scarab beetle, and it was a transcendent existence among the Egyptian gods.

Mongolian gray weevil, two-leaf beetle, leek leaf beetle.

1. Mongolian gray weevil: it is Coleoptera, weevilaceae. It is distributed in Northeast China, North China, Jiangsu, Inner Mongolia, Northwest China and other places. It mainly harms cotton, hemp, millet, cabbage, sugar beet, melon, corn, peanut, soybean, sunflower, sorghum, tobacco, fruit tree seedlings, etc.

2. Two leaf beetles: insect name, for Coleoptera, leaf beetle. It is distributed in various soybean producing areas in China, Japan, North Korea, Russia, southeastern Siberia, etc. The body is small, oval to oblong-ovate, yellowish-brown.

3. Leek leaf beetle: belongs to Coleoptera, leaf beetle. It is distributed in Liaoning, Inner Mongolia, Gansu, Xinjiang, Hebei, Shanxi, Shandong, Sichuan and other provinces. Host leeks, onions, garlic, cabbage. Adults eat leaves, and larvae eat roots and bulbs in the soil.

Beetles are the oldest type of insects, and they flourished in the Upper Jurassic or Lower White Quay periods. At that time, higher plants had not yet appeared, nor did hymenoptera and lepidopteran insects, and beetles were the earliest pollinators in geological history.

The primitive type of beetle has a positive neckline, which is suitable for pollinating some plants with larger, flattened flowers (butterfly or bowl-shaped) than primitive types, and they have a strong smell to attract beetles.
