Do grasshoppers eat other grasshoppers

grasshoppers are veggietarians and if the grasshopper is bigger than another, the bigger one may eat the smaller one
Yes, grasshoppers do eat each other. I had 5 pet grasshoppers and cleaned up after them. They feed on any other bugs, plants, or each other. But I did look in their home that I made and there was nothing in it so it was grasshoppers.

Another answer

Not usually. They generally only eat plants. However, some species may eat other grasshoppers on occasion.
