Aquatic invertebrates were sample monthly from May through September in six wetlands in Yellowstone and Grand Teton National Parks during 1995. Weltlands sampled exhibited semipermanent, seasonal, and temporary hydrologic regimes. Physical and chemical characteristics of wetland water were similar; except for specific conductance, which was either low (less than 60 µS cm^-1), intermediate (270-550 µS cm^-1), or high (greater than 900 µS cm^-1). A total of 187 taxa of aquatic invertebrates were identified from all samples. Almost 70 percent of the taxa collected had not been reported previously in either park. Taxa richness was greatest in semipermanent wetlands and least in temporary wetlands. Among all wetlands, monthly mean abundance ranged from 18,041 m^-2 - 335,975 m^-2. Food webs of semipermanent wetlands were most complex, while those in temporary wetlands were most simple.
