It feeds mainly on the young seeds of plants and soft small insects, and is harmless to people and the environment. "It is also a natural enemy of many pests, such as mosquitoes, maggots and lepidoptera pests. From this point of view, it can also be said that it is a beneficial insect. ”

What are the characteristics of the Chinese leptobucha?
At first glance, the Chinese mantle looks a bit like a cockroach, with a black shell, two tentacles on the top of the head, and three pairs of feet. But this insect is not entirely beneficial to humans. "It's called a because it's greedy." Liang Hongbin, an associate researcher at the Institute of Zoology of the Chinese Academy of Sciences, said that experts have investigated in Inner Mongolia and northern Hebei and found that during the fast-ripening grouting period of millet, the tinge will climb to the spike to nibble.
The Chinese greedy step armor is easily attracted by the light and has a certain "phototropism", so it will appear in our field of vision in large quantities.

Some experts believe that the appearance of Chinese Tsubasa in the community is not only not a bad thing, but also means that the biodiversity of the city is relatively rich and can provide sufficient food for Leptobu.
Encountered how to deal with?
To keep the Tsub out of the door, experts suggest that the most simple "physical" way to deal with it can be done: turn off non-essential lights; Keep the windows tighter and so on.
Once it is found that there is a in the house, the citizens only need to sweep it out with a broom.
