The burrowing is carried out using the mouth parts and special cutting surfaces on the front legs. While these are being used, the mite anchors itself with suckers on its feet. Eggs are laid in small numbers as the mite burrows, and, as these hatch, six-legged larvae climb out on to the skin and search for hair follicles, where they feed and moult (discard old cuticles to grow). In the hair follicles, the larvae show the first nymphal stages, with eight legs.
