In early spring they assemble infields of grass and small grains. Soon they pair and the femalescommence to lay their small yellowish-white eggs upon theroots or bases of the stalks, each laying some 150 to 200 eggs. The eggs are laid from the middle of April until the first ofJune, depending upon the latitude and weather, and hatch intwo or three weeks. As the nymphs grow they often do seriousinjury to small grains and grass, upon which they become fullgrown about the time of harvest. When wheat is harvestedthey spread to oats and soon to corn, but, curiously enough, though.

Control.—The burning over of grass land, and the grass alongfences, hedges, and roads, as soon as it becomes dry enough inlate fall and early winter, is of prime importance to destroythe Inigs after thev have gone into hibernation.
