Biology

for Oriental Cockroach

Eggs ride in a capsule (ootheca) holding about 16 eggs in two rows, taking roughly 42 to 81 days to hatch; nymphs then pass through seven molts to adulthood. Source: https://ask.ifas.ufl.edu/publication/IN316

It is a slow grower: UF/IFAS reports about a year from egg to adult and the Illinois Department of Public Health an average near 18 months — far slower than the German cockroach's two months. Adults live from about a month to six months.
