Everyone knows that grasshoppers disappear once cold weather arrives. Where do they go and what is their strategy for surviving the winter? Most grasshoppers overwinter as eggs. They mate, lay eggs and die in the fall. The female Red-legged Grasshopper, New England’s most abundant species of grasshopper, deposits clusters of eggs one to two inches deep in the soil in the late summer and early fall. During this process, a glue-like secretion cements soil particles around the egg mass, forming a protective “pod.” Each pod is roughly three-quarters to one-inch long and curved. The top third is dried froth, the bottom two-thirds contain 20 to 26 eggs. Each egg is just over 1/10th of an inch long and pale yellow.
In the spring, nymphs hatch out of the eggs, crawl up to the surface of the soil and start to feed on grasses and other herbaceous plants. It takes about three months for them to mature and begin the cycle all over again. (Photo: gravid female Red-legged Grasshopper in late summer)
