Cockroach Insect

I have been watching Cockroach Insect since my childhood. Because I live in the village. There are many forests in the village. And these insects leave the forest and enter the house. So I often notice them coming home from the forest at night and roaming around. They can move well. They have wings. They can fly. I like to see all these insects. I heard that people of many countries eat these insects. But we don't eat. I saw the bird eating. They maintain the balance of the environment.
