The American Giant Millipede (Narceus americanus) is the largest millipede in North America, reaching lengths of up to 5 inches. They can be found in dark, moist environments, often under rotting logs, rocks, and leaf litter. These animals are detritivores, feeding mainly on the same things that give them shelter: decaying wood and leaves. However, they have also been found to enjoy fresh fruit. When acting in defense, the American Giant Millipede may curl up or release a noxious fluid containing benzoquinones. This fluid can temporarily stain skin, known as "millipede burn," and cause mild irritation. Seen above is an example of this species in the Appalachian Mountains at Picklesimer Rockhouse Falls.
