Life Cycle
The female lays 5-60 eggs, which hatch in about two weeks. The larvae immediately start eating, males go through at least five molts and females six over the larval period of five months. The larvae pupates in their larval skin for 11-17 days, and become adults, which start reproducing three days after emerging.
