The authors present dragonfly data collected mainly in central and northern Finland during the summer season in 2023-2025. A total of 27 species were recorded at 65 sites, including 16 species north of the Arctic Circle. This is a significant addition to the knowledge of the fauna of some poorly explored regions in Finland. From a zoogeographical perspective, the most significant is the first record of Onychogomphus forcipatus beyond the Arctic Circle and 270 km north of the current northernmost site. Also Lestes sponsa and Cordulia aenea were found outside the previously known range, and the records of Coenagrion armatum, C. pulchellum, Aeshna grandis, A. serrata, and Somatochlora flavomaculata are crucial for refining the boundaries of their distribution areas. The records of 13 threatened or near threatened species in Europe and the European Union are also valuable
