Arthro- pods serve this purpose because they are abundant and diverse in urban areas, and relatively easy to collect. Over seven years, in the Central Arizona Phoenix area, arthropod communities in three urban habitat categories were collected and compared to arthropods in natural desert using pitfall traps and non-parametric analyses. First, we tested for differences in arthropod composition, abundances, and diversity across habitats and years. Second, we examined how conclusions about arthropod diversity vary with level of taxonomic resolution. We found that arthropod community composition varied among the four habitats at all taxonomic levels tested. In particular, urban mesic habitats had generally lower diversity than natural desert habitats, although with some exceptions. In contrast, mesic habitats had hi
