What is a locust called? What is a grasshopper

Leech, commonly known as leech,The body length is slightly flattened, at first glance it looks cylindrical, the body is about 2 15 cm long and 2 mm wide. The dorsal surface is green with black in the middle, with 5 yellow longitudinal lines, the ventral surface is flat, grayish-green, without variegated spots, the overall annular pattern is prominent, and the body segment is composed of 5 rings, each with a similar width.

10 eyes, arranged in a shape, there are 3 semicircular jaws in the mouth to surround a Y-shaped, when sucking the animal body, use this jaw to drill into **, the body is large, the body length is 60-120mm, the width is 13-14mm.

Living Environment:

It lives in rice fields, ditches, shallow water and polluted pits and ponds, sucks the blood of humans and animals, moves very quickly, swims in waves, and can also migrate in the form of inchworms. It is active every spring and warm, and its spawning period is from June to October, and it often lies dormant in the coastal wet mud in winter, without food or movement, and has strong survival ability.

Habits: Leech is a cold-blooded link, can grow and reproduce in the north and south of China, it mainly lives in reservoirs, ditches, paddy fields, lakes and marshes in fresh water, and is most abundant in organic matter ponds or non-polluted small rivers.

The suitable growth temperature is 10-40, and the northern region enters the dormant hibernation period in the soil when it is lower than 3, and the stinging activity is higher than about 8 in March and April of the following year.

Grasshoppers generally have a flat dorsal and ventral, a narrow anterior end, and are leaf-like or worm-like as a whole.

Body shape can change depending on how much you stretch or how much you eat. The body segments, and the anterior and posterior segments evolve into suction cups. The anterior suction cup is small and often surrounds the mouth; The posterior suction cup is cup-shaped, mostly towards the ventral surface.

Except for spiny leeches, the segmentation of the body is relatively fixed, indicating that they are closely related and have a high degree of specificity.

Leeches, also known as leeches, leeches, mainly grow and reproduce in inland freshwater waters. The leech is slightly flattened in length, cylindrical at first glance, about 2 15 cm long and about wide. 5 cm; The dorsal surface is green with black in the middle, with 5 yellow longitudinal lines, the ventral surface is flat, grayish-green, without variegated spots, the overall annular pattern is prominent, and the body segment is composed of 5 rings, each with a similar width.

Leeches have high medicinal value and are traditional Chinese special medicinal aquatic animals.

The body of the locust has no bristles, the front and rear ends have suckers, the body is muscular, and the body cavity is divided and filled by muscle and connective tissue. Generally, the dorsal ventral is flattened, the anterior end is narrow, and the whole body is leaf-like or worm-shaped. Body shape can change depending on how much you stretch or how much you eat.

Leeches mainly live in reservoirs, ditches, paddy fields, lakes and marshes in fresh water, and are most abundant in ponds with rich organic matter or non-polluted small rivers. The dorsal surface is green with black in the middle, with 5 yellow longitudinal lines, the ventral surface is flat, gray-green, without variegated spots, the overall annular pattern is prominent, and the body segment is composed of 5 rings, each with a similar width. There are 10 eyes, arranged in a shape, and there are 3 semicircular jaws in the mouth to form a Y-shape, when sucking the animal body, use this jaw to drill into the **.

Precautions for being bitten by leeches

Do not pull the leech off with your hands when it bites you, as the leech has two suction cups, which is likely to backfire and make it suck tighter, while hard pulling will cause its mouthparts to fall under the skin and cause infection.

There are many ways to get leeches down, you can pat your arms, thighs or other bitten places, this kind of ** leeches will fall off, and it is a common method to apply thick salt water to leeches. In addition, you can also apply soapy water, e-liquid, wine, vinegar, etc. to the leeche, and soon the leech will fall to the ground.

The leech – also known as the "leech" – is a blood-sucking creature with a relatively large, slightly spindle-shaped body, and a flattened and fat dorsal belly.

There are three types of leeches: the dry locust, the water locust and the parasitic locust.

What to do when encountering leeches? - If you go to work in the fields and fish in the pond, you only see bleeding but no pain, you don't have to be afraid when you see this scene. First of all, don't pull it off with your hands, as it will suck more firmly.

You can pat your arm near where the thigh was bitten so that it can be shaken off. You can also apply soapy water, wine, vinegar, etc. to the body of the locust.

The utilization value of the grasshopper - it is included in traditional Chinese medicine, it can inhibit the activity of thrombin, can prevent fibrinogen from forming fibrin, thereby inhibiting the formation of thrombosis. Moreover, it has the effects of stroke, high blood pressure, stasis, amenorrhea, bruises, etc.

Prospect of artificial breeding - now China has a certain understanding of the living habits of grasshoppers, and there is a relatively complete feeding program, if you want to raise it or can be successfully artificially cultivated, its net income is still very considerable.

What do you think? You know something about locusts, if you accidentally encounter them in the future, deal with them calmly!

The locust specializes in sucking blood, and he also likes to drink the blood of frogmen.

A locust is a leech. The main characteristics of leeches are flat spindle-shaped, with many links; The back is dark brown or dark brown. The body of the grasshopper is slightly flattened, and at first glance it looks cylindrical, with a body length of about 2 15 cm and a width of about 2 mm.

The back of the locust is green with black in the middle, there are 5 yellow longitudinal lines, the ventral surface is flat, gray-green, no variegated spots, the overall annular pattern is significant, and the body segment is composed of 5 rings, and the width of each ring is similar.

The back of the locust is dark green, with 5 longitudinal stripes, and it sucks blood and stores it in the entire digestive tract and blind sac from the pharynx through the esophagus. Grasshoppers have excretory holes in each segment of their body, which open ventrally. The male and female reproductive orifices of grasshoppers are 4 rings apart, and the limb source is guessed to be between the rings.

The front sucker of the locust is easier to see than the previous type, and the rear sucker is more significant and the adsorption force is also strong.

Grasshoppers are produced in lakes, ponds and paddy fields in most parts of China. Grasshoppers are mainly produced in Shandong Weishan, Dongping, Nanyang Lake and other lakes, with the largest output of Weishan Lake, in addition to the province, and sold in the Northeast, Hebei, Shanxi.

The main active components of grasshoppers are macromolecular compounds, such as hirudin, heparin, histamine, kissyphin and amino acids. Hirudin is the strongest thrombin-specific inhibitor identified to date.
