The distribution of algae and insects was examined in two hot spring outflow channels at Waimangu in the Rotorua thermal district. The upper temperature limit for algal growth was 68°c, with maximum biomass occurring at 59–62°c. Two species of Diptera were present on the algal mat, Ephydrella thermarum Dumbleton at 34–43°c and Chironomus cylindricus Freeman at 39–41°c. The composition and temperature relations of the community are similar to those found in thermal regions in other parts of the world. © Taylor & Francis Group, LLC.
