Macroinvertebrate assemblages of inlet and outlet streams were examined in a high elevation cirque comprising two basins in the Swiss Alps. Average taxon richness, with chironomids included as a single taxon, was 10 % of the assemblage at most sites. Chironomid abundance typically was higher in outlets than inlets. An exception was Diamesa zernyi/cinerella, which had greater relative abundances in inlets (24 %) than outlets (6 %). The results suggest that alpine macroinvertebrates, chironomids in particular, are sensitive to subtle differences in habitat conditions and may thus make good sentinels of environmental change to alpine waters.
