The drift classification for stream invertebrates is inadequate for understanding benthos drift in terms of the population dynamics of benthic invertebrates. The deficiencies of the classification can be avoided if instead of considering causative factors, we distinguish drift types in terms of decrease or increase in the biomass of specific groups in a specific stream segment during the course of a day as a result of drift. Based on this approach we propose to distinguish five types of drift: neutral, negative, positive, catastrophic, and pre-imago.
