In Lithuania, there is still a lack of data on the distribution, diversity or abundance of leaf mining moths in some areas. This study presents a research of conducted moths in Alytus district from June to November in 2022. The studies were carried out in seven different locations: the Vidzgiris Botanical Reserve, Kabinės village, Panemuninkai village, Alytus city garden, The 1st Fort of Alytus Fortress area, Mažoji Dailidė and Didžioji Dailidė lakesides, and the area of mound Rumbonys. The aim was to determine the diversity, abundance, tropic relations and the study of Nepticulidae, Gracillariidae, Tischeriidae, Incurvariidae, Elachistidae, Lyonetiidae and Opostegidae moths in comparison with other districts of Lithuania. The focus of the research was on the collection of mines, which were later used to identify the species of moths. In addition, butterflies were captured using a light trap. Temporal genitalia preparations were carried out to identify some species. The PAST software (version 4.11) was used for data analysis and calculation of the statistical analysis results. The study identified 7 new species for the Alytus district: Phyllonorycter cerasicolella, Phyllonorzycter corylifoliella, Johanssoniella acetosae, Ectodemia subbimaculella, Stigmella carpinella, Stigmella oxyacanthella and Pseudopostega auritella. In total 42 species were identified of which belongs to the families of Nepticulidae, Gracillariidae, Tischeriidae, Incurvariidae, Elachistidae, Lyonetiidae and Opostegidae. More than half (64%) of the identified moth species are oligophagous, the rest are monophagous (26%) and polyphagous (10%). The highest proportion of feeding moth caterpillars was found on plants of the family Rosaceae (43 %). Comparing the study of Alytus district, Alytus county ranks third among the 10 counties of Lithuania in terms of the number of identified species. |
