Overwhelming preference of the mites for their natural geotrupine associates (Mycotrupes gaigei Oison and Hubbell, Peltotrupes profundus Howden and Geotrupes egeriei Germar) over non-geotrupine candidates was illustrated in their initial olfactory responses, boarding and pre-attachment behavior, and in choice of final attachment sites.
