Mites, including ticks (Acari) Larval mites have six legs nymphs and adults generally have eight legs. They can be flattened or globular, rounded or elongate, long- or short-legged, and they are not obviously segmented. In some species it is only the larva that is parasitic, in others only later stages mites may feed on blood, glandular secretions or skin debris. They can occur anywhere on the bat. The star-like spinturnicids are most obvious on the wing membrane other mites may also be found here. A great range of mites are found in the fur, and specialist mites can be found on facial whiskers, in sacs on the wings or feet, or in cones of dried plasma on the lips or feet. Some species, such as the ticks, spend more time off the host than on, but they or their cast skins can often be found around the roost. A good introduction to mites can be found in Evans et al. (1961) and a recent review of species found on British bats in Baker & Craven (2003).
