Abstract: 1) A limnological survey of Pua'alu'u Stream, Haleakala National Park, was conducted addressing the following points: a) Verification of the Lentipes concolor abundance in the stream; b) Assessment of the stream's fauna; c) Study of the unique nature of the stream. 2 ) Lentipes concolor indeed proved to be very common in Pua'alu’u. 3) The stream appeared to be particularly suited to this species by virtue of its geomorphology and its consequent species composition and distribution. 4 ) Pua'alu'u proved to be unique in terms of its insect fauna, its flora, and its stream fauna. 5) An hypothesis is developed which may prove to be applicable not only to the potentially rare and endangered Lentipes but which could be the basis of a paradigm for the determination of critical habitats for other Hawaiian freshwater species. 6) The flora of the stream bank is predominantly exotic with dense thickets of bamboo in many areas. 7) The bamboo has had a negative impact on the insect fauna as well as being probably responsible for significant erosion of the stream course banks. 8) The insect fauna below 150 m has been seriously depleted by the activity of the long-legged ant (Anoplolepis longipes). 9) Recommendations for the protection of the stream and its banks are suggested.
