Does mealworm looks different from the adult?

Yes, mealworms look different from the adult. Mealworms are the larvae of darkling beetles and are white, cylindrical grubs with tiny legs. They lack wings and can be up to an inch long. Adult darkling beetles, also known as flour beetles, have two sets of wings, six legs, and are often brown or black with stripes or spots. Their bodies are elongated and narrow with a triangular head, which the larval mealworm does not have.
