Pygmy locusts are small grasshoppers of the family Tetrigidae. About 250 genera and 1500 species are known, most of these living in the forests of the tropics. However, several species are inhabiting temperate and even arctic regions of Europe, Asia and America.
Pygmy locusts are typical inhabitants of moist places in tropical forests: they can be found in marshes, on the ground between fallen leaves and on the border of streams. Several species are semi-aquatic and dive from stones in the middle of streams into the water.
