Where can the longhorn cow be caught

Many people have caught or observed the longhorn cow as a child and have become interested in them. What's interesting is that when you grab it, it makes a "crunch" sound in an attempt to break free and escape. If you tie a thin thread to his leg and let it fly, you can still hear the sound of "camping".

There are many ways to play the Tianniu, such as the Tianniu Race, the Tianniu Pulling Car, the Tianniu Fish, the Tianniu Race, etc., compared to the electric toys that are currently flooding the market, it is much more interesting to play this "natural pet". However, I would like to remind everyone here that when playing, beware of not being bitten by the strong roof of the palate! There is a popular game of "Tianniu fishing" among the people, which is very funny.

The method is in a basin containing water, put a fish-shaped small piece, perforated tie the thread, the other end is tied to the horn of the bull, the length of the line is moderate, the bull is placed on another small wooden strip, floating on the surface of the water, the bull is surrounded by water, cramped and restless, frequently waving the tentacles, similar to fishing, if the fish is out of the water, then the fishing is successful. For example, in the game of two insects, the winner wins by catching the first fish, which is very interesting. The longhorn beetle belongs to the higher body tissue insects.

In contrast, it is like a bizarre creation, just a small piece of crawling intestines! The life history of the longhorn varies depending on the species, some complete the first or second generation in 1 year, and some can complete the first generation in 2 3 years or even 4 5 years. In the same area, the amount of food and the age, dryness and wetness of the infested plants all affect the growth and development of larvae and the number of generations that occur.

It usually overwinters in the trunk of a tree as a larvae or adult. After the adult worm emerges, some need to supplement nutrition, eating pollen, young branches, young leaves, bark, sap or fruits, fungi, etc., and some do not need to supplement nutrition. The lifespan of adults is generally more than 10 days to 1 2 months; But adults overwinter in the pupal chamber for up to 7 to 8 months, and males have a shorter lifespan than females.

The activity time of adults is related to the thickness and thinness of the small eye surface of the compound eye, which is generally thick, mostly active at night, and has phototaxis; Those with small eyes and thin faces are mostly active during the day. The oviposition mode of adult worms is related to the form of mouthparts, and generally the adult of the anterior mouth type lays eggs directly into the rough bark or cracks when laying eggs; The adult worm with a lower mouth first bites into a groove on the trunk of the tree and lays its eggs in the groove. The longhorn beetle mainly feeds on larvae, lives the longest, and causes the most serious damage to the trunk.

When the eggs hatch out of the larvae, the first instar larvae are bored into the trunk of the tree, initially feed under the bark, and after the inage increases, they burrow into the xylem for damage, and some species only stay under the bark to live, not into the xylem. The larvae move within the trunk of the tree, and the shape and length of the moth-eating tunnels vary from species to species. The larvae feed on the trunk or branches, opening their mouths into the bark at a certain distance as vents, pushing out excrement and wood chips.

When the larvae reach maturity, they form a wide pupal chamber, which is clogged with fibers and sawdust at both ends, and pupates in it. The pupal stage is about 10-20 days.

The larvae of the longhorn beetle eat the trunk and branches, affecting the growth and development of the tree, weakening the tree, leading to the invasion of germs, and it is also easy to be broken by the wind. When the damage is severe, the whole plant dies, the wood is bored, and the process value is lost.

Especially on mulberry trees, there are also drops on willow trees, but you should catch less longhorn beetles are pests.

All you have to do is grab the wings on both sides of it.
