Life Stages Of A Mealworm. Larva The second stage of life lasts about eight to ten weeks and is spent as a brown larva. During this stage, it moves about by crawling and it also sheds it's skin several times.
The colour of the egg is white but dusted with age. Female adult darkling beetles can lay hundreds of eggs during their lifespan. The egg is smaller then the picture shown here.
Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult.
They look weird when they are moulting and their old skin has ridges that look like scales.
The egg is smaller then the picture shown here. Pupa During a mealworm's last molt it will turn into a white alien-like pupa. We bought some mealworms for Lili's science experiment.
