What is the difference between a Locust and a Grasshopper?

Answer 1

Physically, not much. Grashoppers tend to be a brighter green, and somewhat fatter, while locusts tend to be a duller brown, and thinner.

However, under the right conditions of weather, locusts eggs will open up after several years of dormancy, and huge swarms of them will spread across the land, darkening the sky, and eating through every leaf and small branch, chewing on all the larger wood products like house posts and tree trunks, and sometimes even eating small animals like birds, and babies. Eventually, they will have nothing to eat, and will turn on themselves in a frenzy of breeding and cannibalism to leave their eggs behind for another season.

Grasshoppers spend most of their life alone, their eggs hatch in a specific amount of time, and they just nibble on leaves a little.
