There are a number of millipede species in the UK; one familiar group includes the flat-backed millipede, which can be found under rocks and in compost heaps in the garden, as well as in rotting trees in woodland. Millipedes are very long, many-segmented invertebrates that live in the soil, under rocks, or under the bark of trees. They are vegetarians, eating mildew and decaying vegetation, and perform a useful nutrient-recycling function in various habitats. They are very slow-moving creatures, but can excrete almond-smelling fluids (cyanide) from their sides if threatened.
