Millipedes (Class Diplopoda, previously also known as Chilognatha) are
arthropods that have two pairs of
legs per segment (except for the first segment behind the head which does not have any
appendages at all, and the next few which only have one pair of legs). Each segment that has two pairs of legs is a result of two single segments fused together as one. Most millipedes have very elongated cylindrical bodies, although some are flattened dorso-ventrally, while
pill millipedes are shorter and can roll into a ball, like a
pillbug. Millipedes are
detritivores and slow moving. Most millipedes eat decaying
leaves and other dead
plant matter, moisturising the food with secretions and then scraping it in with the jaws. However they can also be a minor garden pest, especially in
greenhouses where they can cause severe damage to emergent seedlings. Signs of millipede damage include the stripping of the outer layers of a young plant stem and irregular damage to leaves and plant apices.
