During reproduction, the male grasshopper inserts his spermatophore, a package containing the sperm, into the females ovipositor. The female then lays the fertilized egg pod in the ground, using her ovipositor to insert the eggs about one to two inches underground. The egg pod stays there through the winter, and hatches when the weather has warmed sufficiently. The first nymph to hatch tunnels up through the ground, and the rest follow.
