Darkling beetles are a diverse group of insects belonging to the family Tenebrionidae. They are typically found in various habitats, including deserts, forests, and grasslands. These beetles are known for their dark coloration, which helps them blend into their surroundings and avoid predators. Many species are nocturnal, meaning they are most active at night. These beetles play an important role in the ecosystem by decomposing organic matter and recycling nutrients back into the soil. Some species are also used as food for pets, such as reptiles and birds, while others are studied for their unique adaptations to extreme environments, like desert habitats.
