Color: Green, brown, or gray.
Size: They range in length from one-half inch (1.3 cm) to more than six inches (15 cm) in some tropical species.
These animals live almost everywhere on land. They live in forests, grasslands, and deserts. They even live on mountains. But there are two places where they don’t live—the freezing North and South poles
Feeding: Although they eat many things, they still have preferences. Mating behavior: See how male courts female. Egg-laying: Female digs hole with abdomen. Some grasshoppers spit a brown bitter liquid as a defensive behavior in response to being handled. Use a piece of white paper and gently wipe the grasshopper's mouth if the spit is not evident. Before molting, grasshoppers do not eat and become less active. During the molt, they swallow air to build up pressure to split the old cuticle.
Short-horned grasshoppers feed on plants. Some eat only certain kinds of plants. Others eat any plant they can find. Many grasshoppers eat clover, corn, cotton, soybeans, and other farm crops. Hungry grasshoppers sometimes eat a whole field of corn stalks—right down to the ground.
Most long-horned grasshoppers eat plants, too. However, some eat the remains of dead animals. A few even eat other insects.
Grasshoppers are very big eaters. A large group, or swarm, of grasshoppers can eat up entire fields of grain. Their huge appetites cause farmers a lot of trouble.
A lone grasshopper doesn't do much harm, although it eats about half its body weight in plants per day. But when locusts swarm, their combined feeding habits can completely defoliate a landscape, leaving farmers without crops and people without food. In the U.S. alone, grasshoppers cause about $1.5 billion in damage to grazing lands each year. A desert locust swarm in Kenya in 1954 consumed over 200 square kilometers of wild and cultivated plants.
• Mowing a wide swath around borders of open fields can reduce migration of grasshopper nymphs walking across the mowed boundary.
• Grasshoppers would rather live in a tall stand of grass and weeds than in your garden, so you may want to let a hedge of tall grass grow up near your garden’s edge in late summer. If you keep your garden weeded, grasshoppers will naturally gravitate toward the grassy patch.
• Birds eat grasshoppers, so attracting birds to your yard and garden area helps control the grasshopper population. Birds that frequently visit your yard eat the grasshoppers as they move into the area, thereby cutting down on the number of insects.
• Plant sunflowers, daisies, dill, marigolds, calendula and alyssum in your yard and garden. These plants attract insects that feed on grasshoppers and help you prevent an infestation.
• One way to control grasshopper populations is to eliminate sites where they might deposit eggs. Grasshoppers prefer undisturbed areas for egg laying, so tilling cropland in mid- to late summer discourages females. Tilling may reduce soil moisture and contribute to erosion, but those disadvantages must be weighed against potential grasshopper damage to the next crop.
• Controlling summer weeds in fallow fields has two benefits:
1) If grasshopper eggs are already in the field, there will be nothing for nymphs to feed on when eggs hatch.
2) Fields will not be attractive to egg-laying adults because there is nothing on which to feed.
Also eliminate tall grass and weeds from around any plants you wish to protect (crops, trees and gardens). This makes the area less attractive to grasshoppers and makes it easier for birds to prey on grasshoppers.
