Tidlig oppdagelse og varsling av fremmede arter 2018

Insects were sampled with malaise traps and vascular plants (focus on non-native species) were surveyed in transects at 15 localities (250 x 250 m), mainly in urban areas, in South-East Norway in September and October 2018. Plants were identified in field by botanical experts, insects (Lepidoptera) were sorted from trap samples and identified by a taxonomic expert.
