Young grasshoppers look like miniature adults, though they lack wings. It takes nearly two months for hoppers to become adults. As they grow, hoppers molt five or six times because they outgrow their exoskeletons just as children outgrow their clothes. After the last molt, two pairs of wings are present. The heavier, leather-like outer wings protect and cover the membranous hind wings.
Most grasshoppers are plant feeders, attacking crops such as wheat, barley, corn, rye, and oats.
The migratory grasshoppers, including the locusts, are a serious threat to agriculture. Grasshoppers are typically found in temperate regions. If you put a grasshopper's head under water it would not drown, because grasshoppers do not breathe the way humans do. Along the sides of a grasshopper are a row of ten tiny holes. These are breathing pores.
