Ecology and phenology of stoneflies (Plecoptera) in the northern slopes of the Central Caucasus in winter and spring seasons

The species of winter- and spring emerging plecopterans inhabiting the northern slopes of the Central Caucasus (territory of the Republic of North Ossetia-Alania, Russia) were examined. A total of 33 species were found at 59 sites. These findings expand the knowledge of ecology and phenology of six species for which we knew little. New localities were detected for a few rare stoneflies: Filchneria balcarica Balinsky, 1950, Plesioperla sakartvella (Zhiltzova, 1956), P. brachystyla Zhiltzova, 1988 and others.
