Abstract

It is examined whether caddisfly assemblages collected by light trapping are influenced by altitude. From twenty-nine sites, a total of 29 season's catches were obtained in 1995. The total number of caddisfly species collected was 53, and the number of individuals caught was 11,128. As a result of non-metric multidimensional scaling based on quantitative data, two groups of caddisfly assemblages could be distinguished: those collected in lowland (sites under 150 m a.s.l.) and the others from highland habitats (sites above 150 m a.s.l.). The indicator value method found assemblages and species most characteristic of the two kinds of habitats. Ecnomus tenellus and Neureclipsis bimaculata were the two significant indicator species of the lowland habitat, and Stenophylax permistus was the significant indicator of the highland habitat.
