Abstract: In the years 2004 and 2005 a cross section of 10 kilometres was observed to determine the communities of Lepidoptera in the north of the "Wilderness Area" of the Riisitunturi National Park. 18 species of butterflies and Geometrids were found. Only 3 species (Colias palaeno, Carsia sororiata, Vaccinia optilete) have their main habitat in the open bog areas nearby the summits. They prefer the warm and sheltered areas.

The first-mentioned habitat shows a mixed biocoenosis consisting of species of the open bogs and of two skippers (Caterocephalus palaemon, Pyrgus centaureae). Geometrids (i. a. Xanthorhoe annotinata, Entephria caesiata, Ematurga atomaria), Hairstreaks, Blues and Fritillaries (Callophrys rubi, Lycaena idas, Boloria aquilionaris, Clossiana euphrosyne) dominate in the wooded areas.
