All lepidopterological records and data from five South Bohemian peatlands were revised and analysed along an altitudinal gradient. The selected peatlands are represented by four characteristic montane peat bogs of the Bohemian Forest (Šumava National Park) and one Třeboň Basin peatland complex of the Červené Blato bog for comparative study. The most important Lepidoptera seem to be stenotopic bog specialists (tyrphobionts) distributed near the fragmentary southern frontier of boreal zone in Central Europe. The investigated peatlands are isolated habitats (refugia) for many tyrphophile and tyrphoneutral species endangered by human impacts outside the peatlands. The authors investigated 1,040 species of moths and butterflies on five peat bogs along altitudinal gradient from the Třeboň Basin up to montane/subalpine zone of the Bohemian Forest. The Lepidoptera species were represented by 33 relict species of cold-adapted tyrphobionts, 74 tyrphophilous species preferring peatlands and 716 very diverse and often rare or endangered tyrphoneutrals. Other 217 Lepidoptera species are tyrphoxenous, records of which are accidental only and not characteristic for peat bogs. Species of all the ecological categories seem to be variable with respect to peatland altitude. Habitat similarities calculated by Sørensen coefficient provide evidence about significant uniqueness of every peat bog. From the conservation biology point of view, the most valuable are populations of paleorefugial relict tyrphobionts and some local tyrphophiles, but even for many tyrphoneutral species the peatland habitat is their last refugium in man-made landscape.
