Mr. Nguyen Thi Thanh, Vinh University, said that after 2 days of dancing, adult stink bugs started the couple. The male approached the female, using his beard to approach the female. If you agree, the head of the beard moves continuously then it turns its head. The male crawled with the female and climbed on his back, kicking the female abdomen with her feet. The female will lie dormant, then the male moves down the side of the trough to the female's eggs, turns her head and starts mating.

When they are couples, the children want to stop but the male does not agree, he will try to hold back by turning around to kick the baby on his back, the two children lean their stomachs on each other, then the male uses his legs to hold his belly. children, and children use all their strength on the four strong pedal legs to push the male out and turn the posture. This process always wins the children. After 5-10 minutes of riding the male, the female often moves quickly to hide. The fastest couple time is 30 minutes and the longest is 360 minutes.

The brown- stained brown bug , Andrallus spinidens, is an important species in limiting many plant pests such as green worms, white caterpillars, and deep cavities. This insect is abundant in China, the Philippines, Japan, Malaysia, Indonesia, Vietnam, Bangladesh, Australia (Australia, New Guinea, some places in Europe and North America.
