 Abstract: Abstract Quantitative records of the number and biomass of water-insect adults from a given area of running water courses were obtained by setting greenhouses over small streams. Comparing the results of emergence in two brooks one observes an outstanding equality of biomass, i.e. 4.39 resp. 4.53 gram organic matter/year/m2 in spite of striking differences in numbers and species composition. The faunal differences are significant of the ecological character of the resp. brooks. Emergence records of three subsequent years in the same place show a rather remote fluctuation of individuals in many species and sudden alterations in the abundance of others. The new method seems of considerable value for productivity studies as well as for the faunistic analysis in running waters.
