The answer is the Darkling beetle.
Hence, the answer is insects.
What are Darkling beetles?
Darkling Beetles belong to the family Tenebrionidae. They are a family of beetles found worldwide, estimated at more than 20,000 species.
Many of the beetles have black elytra. Darkling beetles eat both fresh and decaying vegetation. Major predators include birds, rodents and lizards.
The larval stages of several species are cultured as feeder insects for captive insectivores and include the very commonly known ‘mealworms’ and ‘superworms’ and the lesser-known ‘mini mealworms’.
Some species of Darkling Beetles live in the dry Namib desert and have evolved modification that help them collect water from the fog that condenses on their elytra. Raising darkling beetles from larvae through adulthood can be a rewarding biology project for lower school educators.
