The author reports the symposium, which took place in June 2014 in Dubiecko, in the Carpathian Foreland (south-eastern Poland). Symposium consisted of a scientific session, during which presented several speeches were presented, as well as a field session. Field trips were primarily aimed at recognizing the habitats of the representative of alpine biome – Cordulegaster bidentata. We also visited typical of the River San valley water bodies in the gravel pit, where we had a chance to observe Orthetrum albistylum and Crocothemis erythraea among others.
The author discusses the symposium organized in June 2013 in the Kampinoski National Park (central Poland). One scientific session and a several field sessions took place. During the field sessions, at 16 sites 34 dragonfly species were found with one species (Erythromma viridulum) which makes together 53 species known in this area. Moreover, the recently discovered population of Nehalennia speciosa at the transitional peat bog Długie Bagno was studied with respect to its numbers (at least several thousands of specimens) and the characteristic of its habitat.
The authors give 17 new sites of Nehalennia speciosa discovered in the years 2010–2011 in central–eastern Poland. This data is essential due to poor level of studying of this area and the species itself: stenotopic, under protection and very strongly threatened in Poland (EN category on the Red list of dragonflies of Poland). Species co-occurring with Sedgling were also given, indicating autochthonous species (marked with * symbol) and probably autochthonous (#). Among new sites 7 ones have situated in the eastern part of Masovia and 10 in the northern part of the Lublin District. They fill the gap between sites in northern Poland and the Łęczyńsko-Włodawskie Lake District and the areas of Kozienice. Therefore the state of maintenance of the species in the central-eastern part of the country is much better than it was suggested earlier (Bernard et al. 2009). Other discoveries in eastern Poland also confirm this fact (Buczyński et al. 2012; Czachorowski, Czachorowski 2009; Daraż 2011; Michalczuk 2012). The localities of Sedgling known before and new ones probably do not form the isolated range island but they belong to the extension of its compact main part situated in northern Poland. This is even more likely that at least in eastern Masovia there are numerous peat bogs located in forests similar to those described in this paper. This suggests the existence of a large number of yet unknown sites of N. speciosa which can form compact concentrations on which the analysis of satellite maps and geological maps of the Quaternary seem to indicate. In Poland N. speciosa inhabits: I. narrow zone of floating and waterlogged mats of vegetation on the boundary of open water Key Words. Odonata, Nehalennia speciosa, Sedgling, E Poland, new record, distribution area, habitat. table of lakes and small water bodies, and II. at least partially flooded parts of Sphagnum peat bogs and fens, usually at their small depression. Habitats of the first type are dominating (Bernard, Buczyński 2008). Among the localities we studied, we observed two types of environments, however, the rarer second type was more often (Bernard, Buczyński 2008). The preferences of imagines of N. speciosa towards Carex sp., Carex rostrata, Carex lasiocarpa and Eriophorum vaginatum were observed. New data shows that the number of localities in potential gaps of the range of N. speciosa can be large. Therefore taking a look for this species in other areas where such studies have not been conducted is needed.
