In Vespidae, black velvet with black shield and black background and black wasp with black abdomen (also known as Vespidae, Vespidae) are distributed in Hebei, Shandong, Liaoning, Heilongjiang, Jiangsu, Zhejiang, Sichuan, Hubei, Anhui, Jiangxi, Fujian, Guangdong and other provinces in China. These wasps are about 19-27mm long, brown and black, with brown wings. Beehives are large in size. With the increase of bees, the diameter of honeycombs can reach more than 20 cm, and the maximum can reach 40-90 cm. They are usually built on branches or holes in forests, and sometimes under the eaves of rural residents.

The kind you mentioned, I used to call it a black bee, but I don't know what kind it is. Some people call it the iron-billed wasp. My home is in Anhui, and I was stung once when I was a child. At that time, I saw a hole in the bamboo pole and dug it out by hand. I didn't know there were bugs in it. After being stung, my hands began to ache and numb, and then they became stiff and unconscious, and it took a long time to reduce the swelling. Although the black bee didn't take the initiative to attack people, it still got goose bumps later. The most amazing thing is that the holes drilled by black bees on bamboo poles are basically equidistant.
