Most grasshoppers mate in the fall, lay eggs and die. Their eggs are deposited in the soil, in a cluster held together by a frothy secretion that, when dry, forms a rigid covering. The eggs and secretion are known as an egg pod.
The egg pods of grasshoppers vary not only in the number of eggs they contain but also in their size, shape, and structure. A pod can contain from 4 to more than 100 eggs, depending on the species of grasshopper. Grasshopper eggs vary in size, color, and shell sculpturing. Depending on the species eggs range from 1/10th to ½ an inch long and may be white, yellow, olive, tan, brownish red, or dark brown.
Most grasshoppers have laid their eggs by now, and the lingering warmth of the soil is already incubating them. They will soon enter diapause (the suspended development of an insect/insect embryo that occurs during winter in New England) and will resume their development come spring.
