Pest Organisms / Smokybrown Cockroach
Biology
Development is simple metamorphosis through egg, nymph, and adult, with no pupal stage. A female makes a dark egg capsule (ootheca) and carries it about a day before dropping it in a sheltered spot. UF reports roughly 10 egg cases over a female's life at about 20 eggs apiece; UC IPM puts the case near 3/8 inch long and yielding 40 to 45 nymphs. Growth is slow and temperature-driven: UF gives egg-to-adult an average near 600 days, with adults then living about 215 days.
