Water mites are the only mite group with a fully aquatic lifestyle. As a rule, the young stages parasitize on water insects, a small number of species live in freshwater sponges and mussels. They occur in many different water types and due to their great diversity it is an interesting group for assessing water quality.
The Netherlands has a long tradition in water mite research. In the distribution "The Dutch Water Mites" of 2000, 234 Dutch species are treated. The authors report: "The chance of finding species that are new to the fauna of the Netherlands has become small". Nothing was less true. The publication has strongly stimulated the research and many new species have been found in the following years. In the current publication of De Nederlandse Watermijten, three new species are reported for our country: Lebertia holsatica , Sperchon glandulosus and Arrenurus denticulatus . The total now stands at 273, more than 15% more than in 2000.
With the new key in De Nederlandse Watermijten, all Dutch varieties can be registered. Determining is a specialist work. After catching, the mites must be kept in a special liquid to keep the body supple. The animals are no more than a few millimeters in size and therefore a microscope is indispensable. Important characteristics include the shape and growth of legs and all kinds of structures and hairs on the top and bottom of the body. For every species a distribution card has been included in De Nederlandse Watermijten.
