LIGHT-TRAPPED CADDISFLIES (INSECTA: TRICHOPTERA) AS INDICATORS OF THE ECOLOGICAL INTEGRITY OF THE LIŠTICA RIVER, BOSNIA AND HERZEGOVINA

A study of caddisfl y biodiversity and its application for use as indicator species to assess the ecological integrity of aquatic environments was conducted in the area of the Lištica River, Bosnia and Herzegovina. A portable UV light-trap was used to collect caddisfl ies at two sites: the spring of Lištica- Bilo Vrilo and the middle reach of this river in a karstic depression- Mostarsko Blato. From March 2003 to March 2004 a total of 4334 individuals, representing 34 species, were caught. There were signifi cant differences in species composition and abundance between sampling sites. The fl ight periods are shown for all recorded species and studied in detail for twelve abundant species. The species inventories were used for analysing the longitudinal classifi cation of the sampling sites, composition of functional feeding guilds and the saprobic indices.
