What's a bug with pliers on the back of your ass?

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.

Newt belongs to dermatology, with a body length of 5-50 mm. The body is long and narrow and slightly flat. The head is flat and wide, the antennae are filiform, there is no single eye, and the mouth is chewing. The front chest backboard is developed, square or rectangular.

Newt's abdomen can stretch freely, and there is a tail clip made of tail hair at the end. The tail pincers of females are straight, while males are curved. It grows in soil, leaves or rocks and eats omnivores. 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.

Newts are tough 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. Adults like yellow-brown salamanders are about 20 mm long and 4.7 mm wide, which are yellow-brown. The head is reddish brown and shiny, and the head is slightly wider than the front chest back plate. 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.
