Prior to oviposition, she needs to feed on protein-rich material. The eggs are laid on food substrate in batches of six to eight. The oviposition continues for about two months, and the total number of eggs may reach 200. Adults live approximately one year. The number of larval molts varies from five to seven.
Female larvae have one molt more than male larvae.
When ready to pupate, larvae wander away from the food source and bore into any hard substrate they can find. Pupation occurs within the burrow. The cast larval skin and debris from burrowing serve to plug the opening. The pupal period lasts eight to 15 days, but may be prolonged by unfavorable conditions. The duration of life cycle is about two or three months, but it may vary greatly depending on environmental conditions.
