Biology
It develops by simple metamorphosis: egg, nymph, adult. Females seal their eggs in a hardened, purse-shaped capsule (ootheca) holding roughly 14 to 16 eggs, dropping a new capsule about monthly across some ten months for around 150 young over a lifetime. Reaching adulthood takes about 600 days, and Penn State reports a female can live up to about 15 months in good conditions.
