Saw an interesting program once about what made regular old grasshoppers 'swarm' and become locusts. They said that when food starts to become scarce, like during a drought, then the population becomes denser where there IS food. As they get denser and denser, they start to bump against each other as they compete for food. Something about all that contact causes them to change - turn brownish and start to act different. They tested it by taking grasshoppers and keeping them alone for a month or so. Several times each day they took something and sort of brushed their sides. Sure enough, they started to turn brown and act more aggressive.JimWWhite said:If I'm not mistaken when grasshoppers get like that they become known as locusts. We had a locust swarm in Berthoud, CO back in '84 or '85 that devoured everything in sight. They even stripped and ate the paint off of houses. Those aren't grasshoppers - they're locusts, I guarantee you.
Weird huh?
