Dipteran (Bibionomorpha and Tipulomorpha) diversity in dead wood in Lithuania

Abstract

The aim of this study is to compile the species list of Bibionomorpha and Tipulomorpha flies associated with dead wood in Lithuania. Saproxylic nematocerans were studied from 2014 to 2020 in four protected areas and in five different tree species (Populus tremula, Quercus robur, Tilia cordata, Fraxinus excelsior and Alnus glutinosa) of the second stage of decay by using emergence traps. In total, 113 species were identified with Mycetophilidae, Sciaridae and Limoniidae being the most species-rich families. The compiled list of species emerging from dead wood in Lithuania is presented. Fourteen species were reared from dead wood for the first time.
