These cute little bugs crawl here and there in search of muggy stuff. Once they find their desired place, they remain there for a long time.

  • Mealworms have legs and Exoskeleton:

Mealworms are tiny creatures that have legs and are packed with “Exoskeleton.” It means they’ve got a hard body that assists them in burrowing. The term “exoskeleton” refers to the skeleton wrapped around the body, not inside the body, which worms do not have. These pests have six short legs that are not so visible, whereas worms have no legs!!. When a mealworm turns to an adult stage, their legs assist them in fast running. Therefore, we can say that darkling beetles are fast runners too.

  • Mealworms love darkness:

Mealworms are scientifically known as “Tenebrio Molitor’s” who love to live in darkness. Here the wordTenebrio refers to the darkness.
