Recent findings of rare and endangered stoneflies (Insecta: Plecoptera) in Croatia

Only 28 species of Plecoptera were known for Croatia until the last few years when we started intense studies on stoneflies throughout Croatia. During these studies, we stumbled upon some remarkable stonefly species, which are for a longer time absent from many countries in Europe. Some of these species were found in rather rich populations at some localities through the flow of several rivers. For example, Brachyptera monilicornis is living in several smaller and bigger rivers on the north-western border of Croatia with Slovenia. In the same border area live also Taeniopteryx nebulosa, Besdolus imhoffi, Perla carantana, Perla illiesi, and Protonemura julia. Furthermore, on the eastern border of Croatia with Bosnia and Herzegovina, Marthamea vitripennis was found again after one century, together with Perla burmeisteriana, Besdolus imhoffi and mayfly Oligoneuriella rhenana. Besdolus imhoffi lives also in few more rivers in the north-western mountainous area as in the southern Mediterranean part of Croatia. On the northern border of Croatia with Slovenia and with Hungary endangered Xanthoperla apicalis lives. All these stoneflies are included on the recent list of 50 strictly protected Plecoptera species in Croatia.
