Habitat loss and fragmentation are among the most well-known causes of biodiversity loss, non-native organisms for an ecosystem will/can develop invasive behavior that causes significant damage to other ecosystems by competing with native species. These invasive species have been recognized as one of the major factors in the decline of biodiversity. The location of the investigated area near the crossing points of the Western border (both with Hungary and with Serbia), which represented not a few times the "main entrance gate" of numerous insect species, motivated us to study the area of Timisoara in an attempt to create an annotated check - list of insect species,; this paper being an extract from a larger research that was carried out in the green landscaping of the Timișoara metropolitan area. The biological material was collected by usual methods from woody ornamental plants in the USVT Park. The research carried out in 2021 in the USVT Park revealed the presence of 14 species of insects. Most of the species, 7 in number, belonged to Hemiptera order, families: Membracidae, Flatidae, Cicadellidae, Tingidae, Pentatomidae, Aphididae, but the qualitative/aesthetic damage to the ornamental trees was caused by insects from Lepidoptera order, through the larvae of the 4 species: Cameraria ohridella, Parectopa robiniella, Phyllonorycter populifolia, Cydalima perspectalis. Out of the total of 14 invasive species, 4 are highlighted as very abundant and producing mass attacks on various species of ornamental trees. [ABSTRACT FROM AUTHOR]
