Abstract 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.
