The grasshopper belongs to the phyla anthropoids and class insects. You can tell it is an insect by six legs, pair of antennae, and an exoskeleton. The exoskeleton is made of chitin. Five systems in the grasshopper are the digestive, excretory, reproductive, circulatory, and nervous system. This insect is divided into three different parts. These parts are the head, thorax, and abdomen. Grasshoppers breath by expanding and contracting to pump air through holes, called spiracles, along the abdomen and thorax. The grasshopper uses the process of
metamorphosis. Complete metamorphosis goes in this order: Incomplete metamorphosis goes in
this order: Some animals that prey on the grasshopper are beetles, birds, lizards, mice, snakes, spiders, and wasps. Some differences between crickets and grasshoppers is that crickets’ ears are located in their legs, while grasshoppers’ are located in their abdomen. Another difference is that male crickets make sounds by rubbing their legs, but grasshoppers do not do this. Grasshoppers have caused much damage to humans. They have destroyed whole crops of alfalfa, cotton, corn, and other grains. Bibliography
