Why do kowtow worms kowtow ?

Kowtow insects are not actually kowtowing, but just a physical reaction of kowtow insects when they encounter danger, with the aim of escaping. Kowtow worms have a wedge-shaped protrusion on the ventral surface of the anterior thorax.

The reason why the kowtow insect can kowtow is related to its body structure, and it has a wedge-shaped protrusion on the ventral surface of the anterior thorax, which is inserted into a groove on the ventral surface of the midthorax. These two things together form a flexible mechanism. When the muscles in its body contract, the front chest will forcefully close the middle chest, and when it touches the ground, it can bounce up.

Kowtow insects, whose scientific name is kowtow insects, belong to the class of insects of the phylum Arthropods, and are a general term for a class of insects. When the insect body is suppressed, the head and chest can make a prostration-like activity, so it is called a kowtow insect. Its larvae often cause harm to the host.

Morphological characteristics. Adults are dark brown with a narrow and slightly flattened body. The anterior and mid-thorax can move vigorously. When the insect body is suppressed, the head and chest can make a prostration-like activity, so it is called a kowtow insect.

The larvae (needleworm) are yellow or yellowish-brown, elongated, cylindrical, slightly flattened, smooth and tough, about 20 mm long. The common female is 14 to 17 mm long and about 5 mm wide. Males are 14 to 18 mm long and about mm wide. Dark maroon, densely covered with fine golden hairs.

The larvae are yellowish-brown, broadly flattened, with a longitudinal furrow on the back.

The pupae are long spindle-shaped, milky white. Adults are 8 to 9 mm long and about mm wide; The body is slender and flat, black-brown, shiny and yellowish-brown hairy. The larvae are pale yellowish-brown, elongated, cylindrical. The eggs are milky white and nearly rounded.

If you pinch the kowtow insect in your hand, it will keep prostrating. Actually, the kowtow insect is not really kowtowing, it is just an action of turning over and fleeing after it falls.

Introduction: Coleoptera Kowtoe head insect family Percussion family. Commonly known as kowtow insects.

The origin of the name: Once caught, the reason why people will keep prostrating their heads in their hands is a way to escape danger.

The way kowtowers escape danger is very peculiar. If threatened, the larvae of the kowtoller will fall to the ground on their backs with their legs clinging to their sides, and then suddenly "click" and bounce their bodies into the air.

The principle of kowtowing: there is a transverse slit (concave) between the dorsal plate of the anterior thorax and the base of the elytra, and the ventral plate of the anterior thorax has a wedge-shaped process that stretches backwards, which is inserted into the groove of the middle thorax and ventral plate, so as to form a springing structure.

This is not a kowtow worm, this is a longhorn beetle, the larvae eat wood, you can dilute dichlorvos and inject it into the hole where fresh worm droppings fall, and then close the hole with plastic, and the larvae will be poisoned.

<> there are often kowtow insects in the house, and the most likely thing is that there is food to attract them, and the mere dampness will not attract kowtow insects. This beetle likes to eat a variety of fruits, so it's important to check the food stored at home to see if there are any signs of insect gathering. Once the source is found, pesticides are used to focus on killing.

Kowtow insect (windmill insect) is a common small beetle, which eats the seeds, roots and ** of crops in winter and spring, and is a complete harmful insect. When the kowtow insect lies on the ground with its back to the sky and its head on the ground, it will tilt its head back, arch its body, forming a triangular gap, and then suddenly shrink the longitudinal muscles of its back, allowing its chest to suddenly straighten. At this point, its back will slam into the ground.

Under the powerful effect, the body of the kowtow insect will suddenly bounce into the air. Kowtow insects have a pair of well-developed and robust hind feet. Reasons why kowtow insects kowtow:

Kowtow bugs. Kowtow beetles are black-brown beetles. When people grab it, they will see its head and body keep hitting downward, just like kowtowing to the New Year, so people call it kowtow.

The kowtow insect is not actually kowtowing, but the kowtow bug's physical reaction to danger and aims to escape. Kowtow has a protrusion in the forethorax and abdomen that can be inserted into a groove in the midthorax and abdomen, forming a mechanism like a hinge. When the kowtow insect encounters danger, the muscles contract strongly and are ready to retract towards the mid-chest, crash into the ground, and bounce forward as if they were flipping forward.

When it falls, the foot is just pointing down, and as a result, the kowtow bug can quickly escape. When it is pinched, it still has the same reaction, but because it is trapped, it can't bounce up, so it has to keep pressing its head down and hitting a hard object. When you touch a hard object, it becomes a kowtow.
