The 8th Plague?
Swarms of the desert locust, known as Schistocerca gregaria, were considered the eighth plague sent into ancient Egypt as a punishment for suppressing the Jews, according to the bible. Here a desert locust swarm in Israel in 2004.
These short-horned grasshoppers can form highly mobile swarms, comprising more than 30 million locusts per square mile, which can travel up to 90 miles (150 kilometers) a day. Here an image from the 2004 desert locust swarm in Israel.
Desert locusts can put down some food, able to consume the same amount of food that several thousand people would eat, according to the U.S. Department of Energy.
Locusts differ from grasshoppers in that they have the ability to change their behaviour and habits and can migrate over large distances. Here, a swarm of locusts
"A Desert Locust lives a total of about three to five months although this is extremely variable and depends mostly on weather and ecological conditions. The life cycle comprises three stages: egg, hopper and adult. Eggs hatch in about two weeks (the range is 10-65 days), hoppers develop in five to six stages over a period of about 30-40 days, and adults mature in about three weeks to nine months but more frequently from two to four months," states the Food and Agriculture Organization of the United Nations.
