To work with mites (Fig. 3.1), one must first understand their morphology and classification. Other than the need for a good microscope, the major hurdle to mite identification is the scattered nature of the literature. This disarray includes both the variety of languages and locations of the relevant papers and the babel of jargon used to describe mite morphology. Fortunately, in recent years mite morpho-speak has become more homogeneous and several excellent texts exist that provide clear and comprehensive discussions of mite morphology. For those interested in learning to identify mites, we recommend the ‘bible’ of acarologists: A Manual of Acarology 3rd Edition (Krantz and Walter 2009). For those who speak English and who wish to become proficient in the identification of mites, The Acarology Laboratory at The Ohio State University runs a series of short courses during the Northern Hemisphere summer. The Acarology Summer Program has been in existence for over 50 years and both authors learned much of what they know about mite taxonomy there. For an overview of acarological resources see Google or Walter and Proctor (2010).
