How long does it take for darkling beetles to mature?
Two or three weeks
after the mealworm has pupated, a mealworm beetle will emerge. This is known as a darkling beetle. The egg stage typically lasts 7-14 days but low temperatures and humidity can lengthen double this incubation time.
How long does it take for darkling beetles to reproduce?
The mealworms, which are the larvae of the darkling beetle, will need
10 or more weeks
to go through their life cycle and reproduce to make new mealworms. They will change from larvae to pupae, then from pupae to mature beetles. The beetles will copulate and lay eggs in the substrate, which hatch 1 to 4 weeks later.
