Changes in the complex of phyllophagous Lepidoptera (Insecta) in deciduous trees of Kharkiv citi for 50 years

The aim of this work is to compare the species composition of phyllophagous Lepidoptera in deciduous trees of Kharkiv city as of the 1960s and 2017-2020, as well as the distribution of insect species by lifestyle, by the size of individuals, and by the ability to mass propagation. The greatest increase in the number of genera and species was noted in the families Gracillariidae, Tortricidae, and Geometridae, and a decrease in the families Notodontidae and Erebidae. Gracillariidae has been replenished due to 4 alien species: Cameraria ohridella, Macrosaccus robiniella, Parectopa robiniella, and Phyllonorycter issikii. Open-living species predominate in both assessments, however, at the second assessment, the number of species with semi-hidden and hidden lifestyles increased as well as the number of middle-size and small-size species. The eruptive species from the fi rst assessment became rarer, and alien species more often.
