Some grasshopper plagues still exist in Africa. These plagues are caused by desert locusts. The effects of these locusts are much like that of the Rocky Mountain Locust in the United States in 1880's. They bring total destruction to an area. It is not likely that a grasshopper plague could happen here in the US. No Rocky Mountain Locust specimens have been found in more than fifty years and it appears certain that this species that caused so much destruction is extinct. No one really knows why these insects became extinct. Some theorize that it was because of plowing the land by humans or even climatic conditions. But no one knows for certain what happened to the Rocky Mountain Locust.
For more information of Locust Plagues, here are two good web sites.
