It is mainly known as swarm.... But a group of locusts is also known as cloud or plaque..
The leaves, bark, and wood are poisonous to people and livestock.
Locusts are large grasshopper-like insects. They vary in colour depending on the species - normally brown in colour.
Like true insects they have 3 pairs of legs, the hind legs being the largest and are used for jumping. They have two pairs of wings, the outer pair being harder and used to control flight, while the lower pair are more membranous and are used for flight.
Locusts normally solitary, but become gregarious under favourable conditions and will swarm. Swarms of locusts (millions of individuals) are a serious pest during certain years particularly in Africa and Australia where they can literally decimate and entire field to the ground within an hour.
Eating locusts, from the diary of Mr Blunt (quoted in Lady Wentworth's The Arabian Horse): "It is, I think, not generally known how excellent locusts are as food ... the red locust--which is, I believe, the female--is the best eating, and should be plain boiled. No further preparation is necessary beyond pulling off the long legs; then the insect is taken by the wings, his head dipped in salt, and he is eaten just as he is. In taste he resembles green wheat, having a very delicate vegetable flavour. Fried he is less good. also here is a recipe link for locust bisque;

As Geoff Lawton says in his Permaculture Food Forest DVD, "If you have a plague of grasshoppers you ACTUALLY have a deficiency of turkeys". A 1kg turkey will eat 3kg of grasshoppers in a season. Locusts and Grasshoppers are ideal prey for the ground bird habitat.
If you have a snail or slug problem you ACTUALLY have a duck deficiency!
Research at Oxford has proposed that swarming behaviour is a response to overcrowding. Increased tactile stimulation of the hind legs causes an increase in levels of serotonin. This causes the locust to change colour, eat much more, and breed much more easily. The transformation of the locust to the swarming variety is induced by several contacts per minute over a four-hour period. It is estimated that the largest swarms have covered hundreds of square miles and consisted of many billions of locusts. Plagues of locusts appear many religous texts, including one of the biblical Plagues of Egypt, where locusts ate all the crops in the area. So basically, Locust swarms can occur anywhere that there is an over abundance of locusts in one area.
By farting their way into the deep blue sea, although locusts cant swim so nevermind, but their farts cause OCD, Global Warming, and Expired coffee givin to you by your jolly anut soo-shee-cheng.
Locusts, a type of grasshopper, are very hearty and widespread insects. Nearly every continent is plagued by locusts. The only places in which they cannot live are freezing conditions, like Antarctica.
Locusts have several structures on their heads. The antennae help the locust detect vibrations while the eyes help them see.
