The authors give a new site of Nehalennia speciosa in north–eastern Poland: a transitional peat bog in Błaskowizna village (54°15’22”N, 22°49’19”E). On July 4 and 7, 2011 about 10 individuals of the species were observed, with territorial males in it. They inhabited the flooded depression in the center of the peat bog grown with Carex lasiocarpa swamp with addition of: Utricularia minor, Aldrovanda vesiculosa, Menyanthes trifoliata and Dryopteris thelypteris. Aeshna juncea during metamorphosis was also noted there. In other zones of the peat bog, in a buffering zone as well as beaver canals with open water, 12 dragonfly species were recorded, including 9 autochthonic ones (Enallagma cyathigerum, Coenagrion puella, C. pulchellum, Aeshna grandis, A. juncea, A. subarctica, Cordulia aenea, Leucorrhinia pectoralis, L. rubicunda). The discussed site is threatened by drainage and overgrowing by alder and reed (now at initial stage). It requires protective activities. The peat bog in Błaskowizna is only the fifth site of N. speciosa known from the Suwałki Region. This results from the lack of adequately targeted research not the lack of the species itself. The similar diagnosis can be made for just 13 km distant south–western areas of Lithuania where only one site of this species has been discovered so far
One hunting female of Anax ephippiger was recorded on June 3, 2011, in a xerothermic meadow near the Lake Perty in Kleszczówek in NE Poland (54°16’40” N, 22°53’50” E). It is the northernmost record of the species in Poland so far. The area of studies is probably situated within the migrating route of the species whose migrations reach Latvia in this part of Europe. The recorded specimen belonged to the first generation, no data on reproduction and development of the second generation is available.
