    Abstract

    Palsas (peaty permafrost mounds) are one of the typical periglacial landforms found in Arctic regions. In Japan, palsas are found only in the southern part of Hiragatake (43° 37′ N, 142° 54′ E, 1,720 m a. s. l.) in the Daisetsuzan National Park, Hokkaido. To clarify the species composition of aquatic insect communities in a palsa bog, I sampled aquatic insects in ponds from June to September in 2002. A total of 238 individual aquatic insects from 15 species belonging to 5 orders were collected. Among those species, Oligotricha hybriedoides (Phryganeidae: Trichoptera) , Agabis daisetsuzanus (Dytiscoidea: Coleoptera), Hydroporus konoi ( Dytiscoidea , and Sialis sibirica (Sialidae: Megaloptera) were dominant in palsa ponds.
