Orthoptera are an order of insects. (Grasshoppers, crickets, and locusts are major example insects of Orthoptera.) Phylum of the Orthoptera is Arthropoda, because they can be distinguished by 3 parts: head, thorax, and abdomen. Also, they are enclosed in outer covering skin.

The Orthoptera insects are easily seen from everywhere. Most of the Orthoptera and the grasshoppers are found in grasslands and forests. Scaley crickets are found on sea shores. Camel crickets are found in caves. Schistocerca gregaria (desert locust) is found from desert. Mole crickets are found in under ground. Ant crickets are found from ant’ nests. Turks groundhoppers live only on alpine stream gravel banks. Some species live under the water. Most Orthoptera are herbivorous (eating vegetable), but some of are omnivorous (eating animal and vegetable). Oak bush crickets, green grasshoppers, and mole crickets are carnivores (eating animal).

The grasshoppers and wasp-mimicking katydid from Central America are active during day, while most of the crickets are active at night. The wasp-mimicking katydid is a harmless insect. Even though it is named wasp, it does not look like a wasp. It lives in sunny places in rainforests. When night comes, wasp-mimicking katydid does not move much or moves slowly. (Because it has orange color body, it might be shown well at night.) [http://animals.jrank.org/pages/2369/Grasshoppers-Crickets-Katydids-Orthoptera-BEHAVIOR-REPRODUCTION.html]

The Orthoptera like to live themselves. There are exceptions. Sometimes the locusts or grasshoppers unite together as massive swarms. These kinds of swarms are disasters to farmers.

Line 105: Line 102:


One of examples by the swarms of locusts was written in the Bible.  Exodus 10:12-15 said, “''And the LORD said to Moses, 'Stretch out your hand over Egypt so that locusts will swarm over the land and devour everything growing in the fields, everything left by the hail.' So Moses stretched out his staff over Egypt, and the LORD made an east wind blow across the land all that day and all that night. By morning the wind had brought the locusts; they invaded all Egypt and settled down in every area of the country in great numbers. Never before had there been such a plague of locusts, nor will there ever be again. They covered all the ground until it was black. They devoured all that was left after the hail—everything growing in the fields and the fruit on the trees. Nothing green remained on tree or plant in all the land of Egypt.”''

== Edible Insect Orthoptera ==
In this world, about 3,600 species are edible insects and the Orthoptera are one of the examples. The Orthoptera are eaten for food and medical use. (The grasshoppers, locusts, and crickets are the major edible insects from Orthoptera.). The grasshoppers have lots of protein (about 64 percent protein), so they are a very nourishing meal. (Also, they contain lots of vitamin A, iron, and Karyotin.) They conserve lots of nutrition that other food sources do not have, so they are good food for old people and growing children. Japanese people eat the grasshoppers and bee larvae with soy sauce, which is a favorite dish in Japan. [http://nationalzoo.si.edu/publications/zoogoer/2005/4/edibleinsects.cfm]

Caterpillars of many species are rich in potassium, calcium, magnesium, zinc, and iron, as well as B-vitamins. They conserve lots of nutrition that other food sources do not have, so they are good food for old people and growing children.
