Well, this looks thoroughly unpleasant.
A plague of locusts can be a devastating natural disaster. These infestations have been feared and revered throughout history. Unfortunately, they still wreak havoc today.
Locusts are related to grasshoppers and the two insects look quite similar. However, locust behavior can be something else entirely. Locusts are sometimes solitary insects with lifestyles much like grasshoppers. But locusts have another behavioral phase called the gregarious phase. When environmental conditions produce many green plants and promote breeding, locusts can congregate into thick, mobile, ravenous swarms. These swarms can destroy plant life in just a moments time.
