Summary: | During the »Neretva Science Week« in summer 2022, two larvae of Nevrorthus apatelios were found in Eastern Bosnia and Herzegovina. These are the first confirmations of the species in the country since a single observation of one adult from Sarajevo almost 100 years ago. New records come from two sites of the upper course of the Neretva River, near Ulog village: one larva was found in a benthic fauna sample collected at the river bottom near Rastovac, while the second was pumped from the river interstitial at depths 30-60 cm, in the area near Cerova. Based on these findings we provide a description of the larva. Nevrorthus apatelios lives in highly oxygenated waters, and is a good indicator of clean waters. We discuss the potential reasons for rare observations of the species in the country, and conservation implications in light of ongoing environmental pressures in the currently pristine part of the upper course of Neretva River.
Med »Tednom znanosti na Neretvi« poleti 2022 sta bili v vzhodni Bosni in Hercegovini najdeni dve ličinki vrste Nevrorthus apatelios. To je prva potrditev pojavljanja vrste v državi, vse zabeležbe enega odraslega osebka v Sarajevu pred skoraj 100 leti. Vrsta je bila tokrat opažena na dveh lokacijah v zgornjem toku reke Neretve pri vasi Ulog: ena ličinka je bila najdena v vzorcu bentoške favne, zbranem na dnu reke pri Rastovcu, medtem ko je bila druga najdena v vzorcu vode, načrpane iz rečnega intersticija na globinah 30-60 cm na območju pri Cerovi. Na podlagi najdb podajamo opis ličinke. Nevrorthus apatelios živi v vodah z visoko vsebnostjo kisika in je dober kazalec čistih voda. V nadaljevanju razpravljamo o morebitnih razlogih za redke najdbe te vrste v državi in o varstvenih posledicah, v luči nenehnih pritiskov na okolje v tem za zdaj še neokrnjenem delu zgornjega toka reke Neretve. Apstrakt. Novi nalaz vrste Nevrorthus apatelios H. Aspöck, U. Aspöck & Hölzel, 1977 (Neuroptera: Nevrorthidae) u Bosni i Hercegovini – Tokom »Sedmice nauke na Neretvi« u ljeto 2022. godine u istočnoj Bosni i Hercegovini pronađene su dvije larve Nevrorthus apatelios. Ovo su prva zapažanja vrste u zemlji od prije skoro 100 godina od poslednjeg opažanja. Novi podaci dolaze sa dva lokaliteta gornjeg toka rijeke Neretve: u blizini sela Ulog jedna larva je pronađena u uzorku bentoske faune sakupljenog na dnu rijeke kod Rastovca, dok je druga ispumpana iz riječnog segmentaa na dubinama 30-60 cm, u okolini Cerove. Na osnovu ovih nalaza dajemo opis larve Ne |
