Locust on lettuce

This is a lone locust on lettuce leaves. The locust is not afraid. Even when you touch a leaf of lettuce, the locust does not run away. I managed to catch this locust. I didn't kill. I released this locust outside the garden. When the locust is alone, it's not scary. It is very bad when there are a lot of locusts. Then these insects can eat everything around. By the way, the salad has already outgrown. It's an old lettuce. It needs to be torn out.
