Millipedes are long, cylindrical-shaped insects. They range from 5/8 of an inch to 4 inches in length, and range in color from brown to black. They are a worm-like creature made up of many segments. Attached to each segment are two pairs of legs. Millipedes are generally found in locations that are very moist and contain organic matter that is decaying, such as logs, leaves compost heaps, and so forth. The females lay up to 300 eggs in their lifetime in nests located in the ground. The young only have seven segments and three pairs of legs, but as they molt, the number of body segments and legs increase.
