Two days after mating, females usually face down, first discharging foamy substances from the abdomen, and then laying eggs on them in turn. The foam-like substance solidifies rapidly, forming a hard egg sheath. The traditional Chinese medicine in the egg sheath is called "ootheca ootheca" or "ootheca ootheca ootheca".
