    Grasshoppers generally lay eggs in the upper layer of soil in undisturbed areas in the late summer through early fall. These eggs overwinter and start hatching into small nymphs when temperature begins warming up in early spring. Newly hatched nymphs start feeding on the host foliage. They can also move quickly from one field to other fields in search of food. While feeding, they develop through 5- 6 stages and become adults. Under favourable conditions, grasshoppers can complete one generation in a year.
