Abstract

BackgroundIn 2016, saproxylic Diptera associated with aspen (Populus tremula L.) logs were studied in the Kivach Nature Reserve, Russian Karelia, using trunk emergence traps.New informationEleven rare species of Diptera (families Limoniidae, Scatopsidae, Axymyiidae, Mycetophilidae, Sciaridae, Platypezidae, Syrphidae and Clusiidae) with poorly known distribution and ecology were recorded. For each species, basic diagnostic characteristics were provided along with the information on microhabitats. An attempt was also undertaken to outline possible associations with wood-decaying macrofungi using nonparametric correlation.

Highlights

Saproxylic Diptera have never been specially studied in Russian Karelia, except for certain groups partly associated with wood-decaying fungi (Yakovlev 1988, Yakovlev 1993, Yakovlev 1995, Jakovlev 2011)
Trunk emergence traps have some benefits in comparison with other methods traditionally used for collection of wood-living Coleoptera and Diptera
This study once more demonstrates the effectiveness of the method and shows the importance of large dead aspens for supporting diverse saproxylic insect communities
