| Abstract [eng] |
Lithuanian moths (Lepidoptera) were studied by various researchers for a long time, but mostly only episodic studies were carried on. There are little data concerning nocturnal Lepidoptera investigations of concrete district. Methods and results of nocturnal macrolepidoptera research in agricultural landscape in Ignalina administrative district are described in this work. Analyzed species belong to superfamilies Geometroidea, Bombycoidea, Drepanoidea, Lasiocampoidea, Noctuoidea and Hepialoidea. The material of nocturnal Lepidoptera was collected in Antagavė and Stagalėnai localities (Ignalina administrative district) during May and October 2008-2010. Jalas model automatic light trap with Philips ML 160W lamp bulb was used. Ethyl acetate was used as a killing agent. There were 169 moth species collected in Antagavė and 201 in Stagalėnai with the total number of 13244 individuals. Stagalėnai is in Aukštatija national park. In this village found 33% of the national park known species. There was no eudominants or dominants. The most abundant species were Rivula sericealis (species made 3,89% of all individuals in Stagalėnai), Xestia (Megasema) c-nigrum (3,41%), Caradrina (Caradrina) morpheus (3,12%). 26 macrolepidoptera species made more than 1% of all individuals. They characterise the community. Most abundant species in Antagavė were Noctua pronuba (7,96%) and Caradrina morpheus (6,39%). They are dominants in this territory. Greatest abundance of species and individuals was registered in July. |
