The Darkling Beetle, which is in the form of a 2-inch worm, is capable of eating and digesting Styrofoam. Although their diet mainly consists of wheat bran, they have managed to gain weight and not expire after the consumption of this inorganic substance. If scientists can understand what is behind this ability, it could aid in solving the problem of what to do with the excess Styrofoam being produced. When given antibiotics the larvae were unable to consume more of the substance. This led scientists to believe that the antibiotics were destroying a particular microbe in their digestive system that was responsible for digesting Styrofoam. Studies in Australia with the mealworm found similar results. These worms were able to consume the Styrofoam packing peanuts without it doing any harm to their system.
