Between 12 and 23 July 2006, dragonflies of selected localities in the Vasyugan Plain, West Siberia, were studied by Rafał Bernard and Oleg Kosterin. The article presents personal impressions of the first author from this expedition, partly based on the odonatological results. Our investiga- tions were focused on the largest in the world complex of Sphagnum bogs and fens, and on rivers flowing between them. Additionally, smali anthropogenic water bodies were also visited. In total, 34 odonate species were recorded. An important result of our expedition is the picture of the summer aspect of the odonate fauna in these mostly primeval and remote boggy areas, with the flourish- ing complex of peat-moss bog species and an interesting species composition in rivers. Nehalennia speciosa (the main aim of our expedition) and Aeshna subarctica, both species poorly known and considered to be rare in Siberia, appeared to be omnipresent
