The Lifecycle of Mealworms
Understanding the lifecycle of mealworms is crucial for successful breeding. Mealworms, scientifically known as Tenebrio molitor, undergo a complete metamorphosis with four distinct stages: egg, larva (mealworm), pupa, and adult beetle. This transformation process takes approximately 10 to 12 weeks, depending on environmental conditions.
The cycle begins with the adult beetle laying eggs. A female beetle can lay hundreds of eggs over a few months. These tiny, white eggs are laid in the substrate and typically hatch within one to two weeks. The emerging larvae, known as mealworms, are light brown and grow through several molts until they reach their full size.
During the larval stage, mealworms are voracious eaters, consuming organic material and growing rapidly. This stage lasts for about 8 to 10 weeks. After reaching maturity, the mealworms enter the pupal stage, where they don't eat and remain inactive as they undergo transformation into beetles. The pupal stage lasts for 1 to 3 weeks.
Finally, the adult beetles emerge from the pupae. Initially, they are soft and white, but they darken and harden within a few days. Adult beetles live for a few months, during which they reproduce and continue the cycle. Understanding this lifecycle is essential as it dictates the care and environment needed at each stage.
