The study is devoted to the study of individual indexes saprobity larvae of caddisflies (Trichoptera) from water bodies of Kabardino-Balkaria (Central Caucasus). The results of the work are based on years of in-situ observations, qualitative and quantitative samples of hydrobionts from the rivers and streams of the CBD. Sampling was performed with the help of water nets (qualitative test) and bentometra Sadovsky (quantitative samples). It is established that the fauna of caddisflies Kabardino-Balkaria are endemics and subendemics Caucasus. This circumstance did not allow to use them for biological assessment of water quality in rivers and streams. Our studies have clarified the indicator weight of about 50 species of caddisflies. It was found that the majority of species of caddisflies dwells in spring the rivers and streams, and only a small part of it inhabits rivers with glacier power. All types with very few exceptions belong to the group of xenosaprobic and oligosaprobic. The work gives the individual the saprobity index for most species of caddisflies. The results of investigations are used for creation of the system of surface water quality biomonitoring in the North Caucasus.
