…takes a long time for the mealworm to develop; the development from egg to larva and to adult beetles can vary between 280 and 630 days. The development variate so much because they are highly depende on the temperature and humidity of the environment as well as the nutrition of the larva. The ideal temperature for the mealworms is 26 degrees. When the larva is fully developed, it will pupate. This stage lasts just two weeks, after which it is a f…

The development from larvae to fully grown woodboring beetle can take up to 8…
