According to Sciences 360, a locust is a type of grasshopper, with different behavior. Locusts can exist alone or in communities, while grasshoppers only exist in solitary states. If a locust can find food it remains alone like a grasshopper; but when a locust must compete for food it is forced to congregate in a group and release serotonin. Serotonin causes locusts to change colors, become stronger and breed faster.
Grasshoppers are insects found throughout most of the world. They live in fields, meadows, forests and woodland. Grasshoppers have a three-part body consisting of the head, thorax and abdomen. They have six legs, four wings and two antennae. The two back legs are used for jumping and the four front legs help the grasshopper walk and hold prey, explains A-Z Animals.
Grasshoppers eat grass, weeds, leaves and other plants. Bio Kids Critter Catalog states that some grasshoppers eat toxic plants and keep the toxins inside their body to prevent from being eaten. Predators of grasshoppers include: reptiles, other insects, mammals and birds.
Female grasshoppers lay their eggs in a pod a few inches under the ground during late fall to early winter. The grasshopper eggs wait until it is warm to hatch. Grasshoppers only survive as adults for a matter of months; they die when exposed to cold winter weather, according to Bio Kids.
