4 images here portaying this millipede. Growing up to a length of 25 mm (1 in), it has rows of dark spots along its sides. It spends part of its life cycle living in leaf litter, and the rest in rotting wood. Feeding on dead plant matter, it helps with recycling to great effect. It is fairly common and widespread throughout Britain, and is found in woodland and gardens. Double-click images to enlarge.
