There are many insects in nature, which are used to protect themselves for their own skills. For example, the dead-leaf butterfly we saw on TV will imitate the appearance of dead leaves in order to disguise itself from predators, and hide in these leaves and feel integrated with them, so we can't find it without looking carefully. There are also stick insects, which are very similar in color to parasitic trees, and then lie motionless on the trees just like ordinary twigs.
There are also some insects that drive away natural enemies not by appearance, but by the gas emitted by themselves. Like we always say? Bitch girl? In fact, its scientific name is also called aspongopus. Although it smells bad, many people will eat it as food or medicine. Aspongopus is about 2 cm long and has wings, so it can fly. Generally, eating plants and sucking their juices, such as watermelon and wax gourd, are their shelters.
Aspongopus also has certain medicinal value, which is mainly used to treat stomach cold and abdominal distension. When we are usually weak or sometimes unable to eat, we can take some aspongopus to relieve these symptoms. Although aspongopus smells bad and looks ugly, aspongopus itself has a strong bactericidal effect and can promote blood circulation in our body. Generally speaking, aspongopus only releases smells to scare off enemies when it is hurt, and these smells need to be accumulated to form. This gas is still irritating to human beings.
