What kind of bug is this?

Newt (pinyin: qúsǒu, sound: Qu) belongs to the winged suborder of insects. Newts are commonly known as symbionts, symbionts, or scissors worms, commonly known as "ear-clip worms", because their females will lie on eggs like birds waiting to hatch.

The centipede is an incomplete abnormal insect, so some people believe that it will crawl into people's ears, but it doesn't happen very often. The body length is about less than 1 cm to 5 cm, the abdomen is flexible, and there are tail pliers made of tail hair at the end. The female's tail pliers are straight and the male's is curved. They grow in soil, under fallen leaves or rocks and are omnivorous.

This insect has a high degree of maternal love. Female insects will clean the surface of eggs from time to time to prevent the eggs from being damaged by fungi, and even take care of the larvae until they leave the nest. Newts are not closely related to humans. A few species are harmful to flowers, stored grain, stored fruits, silkworms and fresh insect specimens, and some species are ectoparasites of bats and rats. Dermatophytes generally like to be active at night and often hide under dirt, stones, dead branches and garbage during the day. The glandular folds in the third and fourth abdomen of salamanders can secrete special smells to drive away enemies. The tail needle is a powerful weapon for defense. When you are frightened, you will often lift your abdomen and open the double needles to scare you, but when you meet a strong enemy, you will often pretend to be dead. Female insects have special habits of protecting eggs and raising young. Female salamanders will protect their eggs like hens, and sometimes they will catch worms and feed them to nymphs until they grow up. In the insect world, they can be regarded as loving mothers Most salamanders are omnivorous or carnivorous species, and most of them live in cracks in bark, rotten wood or fallen leaves. They like humidity and darkness, and many species are used to walking at night and flying in the light.

The salamander belongs to the order Dermatoptera, with a body length of 4-35 mm and a long, narrow and slightly flat body. The head is flat and wide, the tentacles are filiform, there is no eye, and the mouth is chewing. The front chest backboard is developed, square or rectangular. The body surface is like leather and shiny. Winged or wingless. With wings, the front wings are specialized into tiny skin wings; The hind wing is large, membranous, fan-shaped or slightly round, and folded vertically and horizontally under the front wing at rest, but it is often exposed outside the front wing. The tail beard is shaped like a hairpin. There is no ovipositor.

Newt structure

The head is slightly wider than the chest backboard. The antenna is yellowish brown with 25-29 nodes. The first node is the largest and has a weak foundation, which is probably the sum of two or three nodes. The second and fourth nodes are smaller and have roughly the same length. The third node is about twice as long as the second node. It grows gradually from the fifth section to the seventeenth section, and gradually tapers to the end, and there are several slender sections at the end. The front chest backboard is clear brown, the middle line of the back is brown, the sides are parallel, and the rear edge is curved. The diamond-shaped part is missing, and the abdomen of the male worm increases from the base to the end, which is dark brown, the tail is far away from the left and right, and the tip is dark brown. The tail of the female worm is narrow in abdomen, close to the left and right, slender and isomorphic, with micro-teeth on the inner edge. There is a short thorn in the center of the inner edge of the male worm. The front wing is yellow-brown at the junction and black-brown at both sides. The hind wings are developed and are long yellow-brown. The feet are light yellow.

Newt with spare sexual organs: A male newt has two penises, and the length of each penis is greater than the length of the newt itself. The penis of this insect is still very fragile, and it will break if you are not careful, which is why it has two penises. In the salamander suborder, the tail whiskers are not segmented and are hairpin-shaped. The shape of hairpin often changes with different species, and even different individuals of the same species can have different shapes. The tail hair of male insects is more developed than that of female insects, and the tail hair of the genus Rattus is needle-shaped and not segmented. Hairtail can be used for defense, predation and courtship. The shape of male genitalia often varies from species to species. Arachnida and Arachnida have two male stems, and most species of males have only one male stem.

The characteristics of this purpose can be summarized as follows: the front wing is short and the rear wing is like a fan vein bone; The tail is hard and hairpin-shaped, and the salamander protects the egg like a chicken hatched.

It is easy to observe salamanders on wet grass and leaves in the wild. When you first meet this worm with a sickle-shaped tail clip, you will be shocked, and you will be afraid of being caught accidentally or being poisonous. In fact, they are very cute little insects. When they are harassed, they will not take the initiative to attack each other, but will also pretend to be dead and run for their lives! Of course, this tail clip is also their defensive weapon. When they are frightened, they will occasionally hold a double-clip demonstration. In addition, the gland folds in the third and fourth segments of the salamander's abdomen can secrete special smells to drive away enemies.

Try to keep the house dry, especially the bathroom clean. You can buy a bottle of insecticide aerosol and spray it when you see it!

However, I suggest you do a good job in indoor hygiene. As long as you keep good indoor hygiene, this kind of bug won't settle in your home.

Related legends

[Newt protects eggs]

Newts protect eggs.

Female salamanders who lay eggs will attach themselves to the human body through their claws. At midnight, when people are asleep, salamanders will crawl into people's ears and enter people's brains. Then the salamander will carefully cut off the human brain nerve so that the poor host will not notice it. It will lay thousands of eggs. After four days, these larvae will hatch and feed on soft brain tissue. At this time, the host has heard stark's madness, and in the end they will die miserably.

The above legends are just legends and have no scientific basis.

Tianjin people call it a fire trap, and Jidong people call it a trap bug [1].

Biological properties

1. Annual life history: Japanese salamander overwinters as adults and nymphs in the soil in northern Jiangxi.

[Newt mating]

Newt mating

In late April or early May of the following year, overwintering adults began to move, feed and reproduce. Spawning begins from mid-May to late June. Two generations can occur in this area throughout the year.

2. Activity: Japanese salamander is a nocturnal insect, which hides in the ground or in the litter or the bracts of cotton bolls during the day and comes out in cloudy days or in the evening. The female worm has a pile of ten eggs, and has a strong habit of protecting eggs. Once they are frequently frightened or encounter inappropriate situations, they will move their eggs or eat them. Adults have phototaxis.

3. Predation: According to the indoor determination (1987), it can prey on 46 kinds of insects and many kinds of cotton pests: tigers, cotton bollworms, cotton bridge builders, Jin Gangzuan Ding Dian, Spodoptera litura, red bollworm, short-fronted negative locust, cotton aphid and so on. In particular, the cotton aphid preys heavily, and an adult Japanese salamander can prey on cotton aphid 179.20 every day on average, up to 275 at most.

Shape, white. Nymphs are 4 ~ 5 years old, and their appearance is similar to that of adults, but their tails are thin and spike-shaped. Wing buds appear at the second instar and overwinter as eggs. Female insects have the habit of protecting eggs and raising young. Female insects lay eggs in caves under rocks or soil, and then lie on or guard the eggs. Young nymphs live with their mother.

Its governance should emphasize prevention and comprehensive management.

1, pay attention to the cleanliness of the home.

2, physical and mechanical prevention: control the atmosphere, lighting.

3. Chemical control: spray methyl pyridinethione or methyl bromide for fumigation (fumigation is very harmful to human body, so pay attention to ventilation in time after fumigation, and it is dangerous to enter after the smoke dissipates, so use it with caution).

4. Biological control: controlling pests through pathogenic microorganisms or natural enemies. [2]
