Ephemeroptera nymphs and Heteroptera nymphs and adults were collected from three elevations in each of three watersheds on Doi Inthanon and Doi Suthep mountains in northern Thailand. Samples were collected from distinct mesohabitats including leafpacks, riffles, waterfall rockfaces, pools, and margins. Comparisons of taxonomic richness and compositional similarity were made among elevations, mesohabitats, and watershed within each taxonomic order. Differences in habitat association between Ephemeroptera and Heteroptera are discussed.
