Millipedes have long bodies with 2 pairs of legs on each segment. New segments and pairs of legs are added each time the millipede sheds. Since it continues to grow and shed throughout its lifetime it is difficult to say how many legs an individual has without counting! The common millipede in southern Arizona is a dark reddish brown. Normally reaching around 5" long. They like to forage for decaying material and are mostly nocturnal but love moving around after a nice summer thunderstorm. They spend most of their time underground. If disturbed, they roll into a coil. If threatened, they can ward off potential predators with a nasty tasting chemical from openings along the sides of its body. They don't bite. Eggs are laid in concealed or underground areas. Millipedes can live over 10 years!!
