Entomol. 55, 53– 71. For several years the author and colleagues in the foundation Siste Sjanse (BioFokus) have collected freshwater organisms at many localities in Norway. The more interesting of these findings are presented below, focusing mainly on redlisted species and species new to specific geographical regions. Some species are also new to the Norwegian fauna.

In general, two publications are the basis for determining whether a species is new to a region A large number of freshwater localities (about or not: Aagaard & Dolmen (1996) and Coulianos 750) have been visited over the years (se (1998). Several later publications have been Figure 1), and approximately 8000 entries (i.e. accounted for, but several have also surely been combinations of species/locality/date) have been missed, and therefore some of my records may databased, some 6000 of these being insects.
