Do slugs summon evil spirits? The old man said to raise slugs to ward off evil spirits. Is there such a saying?

No, I haven't heard of it.

Fruit is the general name of some large songbirds of Insecta, Orthoptera and Tettigonidae. It is big, looks like a grasshopper, has a grass-green body and slender tentacles. The front wings of male insects rub against each other, which can make a "containing" sound, crisp and loud. I like to eat melons, fruits and beans. People raise and watch in small bamboo cages. As an ornamental and recreational insect, it has a long history in China. For example, in Guyi area (now Yixian County, Hebei Province), there is a history of catching slugs in cages for hundreds of years.

Guoguo has many aliases, such as brother and Guoguo. Guo Guo is widely distributed in China, and it is called the three major singing insects together with cricket and water hyacinth. The food in Guo is mainly beans, vegetable leaves and grasshoppers. Male slugs have a loud voice and are deeply loved by the majority of Dendrolimus punctatus enthusiasts.

The body color is green, and a few are light brown. The antenna is 60mm developed, with 2 compound eyes and 3 monocular eyes. The front chest backboard is wide, and the lower edge of the backboard has a yellow edge. There are 1 pairs of conical spines in the thoracic web, and the posterior thoracic spine is the largest. Attachments 4-4-4, 1-3 are provided with foot pads, and the first attached foot pad of the hind foot is divided into two pieces. The distal distance of tibiofibular joint of hind foot is 6, the back is 2, the abdomen is 4, and the middle is 2. The hind leg joint is slightly longer than the tibiofibular joint.
