This kind of bug often appears on the wall recently. What is this? How did it come into being?

Newt, also known as splint worm, finger-cutting beetle, splint worm or scissors worm, ear clip worm and second female clip. It is an omnivorous insect. Abundant in tropical and subtropical regions. Often live in cracks in bark, rotten wood or fallen leaves, and like wet and dark environment.

Earworms (Pinyin: qúsǒu, sound: Qu Lao, English name: earwigs) are a winged suborder of insects. Newts are commonly known as plywood worms, finger-cutting beetles, plywood worms, or scissors worms, commonly known as "ear-clip worms", because their females will lie on the eggs like birds and wait for hatching after laying eggs.

Newt, an incomplete metamorphosis insect, molts 5 times. Their characteristics are similar to those of their parents, except that each molting will increase the number of individuals and tentacles. Newts like narrow spaces. Some people believe that they will crawl into people's ears, but in fact they don't happen very often. This legend only comes from the English name of the earworm, which literally translates as "earworm". The earworm is named because its wings look like human ears when they are completely open! 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. The front wing of the common salamander is short and wingless, which is used to protect the large fan-shaped rear wing. The abdomen can move and stretch, with a pair of pliers-like appendages, usually straight for females and curved for males.

This kind of insect salamander has a high maternal love, and the female insect will clean the egg surface from time to time to avoid the harm of fungi and protect the egg from being preyed. This kind of care will last for a while after the eggs hatch. Female insects bring food into the nest to feed their larvae, or spit out some food they feed. Eventually, nymphs had to be dispersed when they grew up, and mothers began to pay attention to their potential food. The relationship between salamanders and human beings is not very close. 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. They can be regarded as loving mothers in the insect world! 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.
