Mealworm beetle

The mealworm beetle (Tenebrio molitor) is a species of darkling beetle that is native to many areas of the world, including Europe, the Middle East, and parts of the United States. Mealworm beetles are dark brown in color, about one-half to three-quarters of an inch in length, and have three pairs of legs. They are voracious eaters, and feed on a variety of organic materials, including grains, flour, dried fruit, and even dead insects.

Mealworms can be found in a variety of environments, including beneath bark or in logs, or in the soil or stored grains in pantries, sheds, and barns. They are most often seen in their larval form, which looks like a yellowish-white worm. After 7-19 molts, the larvae will form a dark brown pupa, which will eventually emerge as an adult beetle. Mealworm beetles are considered a beneficial insect, as they are natural decomposers, helping to break down plant and animal material into the soil. In addition, mealworms are sometimes kept as food for reptiles, amphibians, and birds, and are even used in some cultures as a food source for humans.
