Family Aeshnidae Rambur, 1842

Aeshna juncea (Linnaeus, 1758)

Fig. 4C, 4D

Material examined. RUSSIA: Kamchatka Peninsula, the Valley of Geysers , 54.4376°N, 160.1389°E, 13 August 2014, Lakelet Medvezhie, 1 larva, Aksenova & Soloviev leg.

Field observations. This larva was collected from a shallow and swampy geothermal lakelet with clay bottom. We did not measure temperature in this water body but it ranges from 30 to 38°C ( Lobkova et al. 2012).

Distribution. Holarctic species ( Haritonov 1986). It was recorded as an abundant species, which can successfully develop in warm waters, in geothermal areas of Eastern Siberia ( Borisov 2014, 2016; Popova & Matafonov 2015). There is a record of imago near a geothermal site in Kamchatka ( Dumont et al. 2005) and larvae from the Valley of Geysers (as Aeschna yuncea [sic!]; Lobkova et al. 2012).
