The Norwegian Institute for Nature Research (https://www.nina.no) conducts a general monitoring of terrestrial insects in Norway since 2020, on behalf of the Norwegian Environmental Agency (https://www.miljodirektoratet.no/). As of 2023, the monitoring program cover semi-natural land in the regions "Sørlandet" (sout-west), "Østlandet" (south-east), Trøndelag (middle), and "Nord-Norge" (northern). In addition, we monitor the forestst in "Østlandet". Expansion to semi-natural land in the "Vestlandet" (western) region is scheduled for 2024. Expanded coverage of forest ecosystems may occur in the future. The monitoring is based on passive sampling through malaisetraps with addition of windowtraps in forests. Identification of insects is mainly done through metabarcoding after a soft lysis of the material. Caution should be excercised when interpreting occurrences of single species, as the metabarcoding and bioinformatics may contain errors. Three possible errors to be aware of: 1) false positives of some species ...
