The mouthparts of orthopterans are modified for chewing plant material; in fact, orthopterans can be serious agricultural pests in certain areas.
The oldest fossil orthopterans are Pennsylvanian in age; that is, about 300 million years old. The fossil grasshopper shown at the right of the page is much younger, only a few tens of thousands of years old; it is from the McKittrick Asphalt of southern California, a fossil-bearing tar deposit (very much like the famous La Brea tar pits in Los Angeles). Today, there are about 80,000 species of orthopterans. Some, like the swarming locusts, are serious pests and destroyers of vegetation. Others, we are told, are remarkably tasty and nutritious when properly prepared.
