New records of ten invasive insect species in Romania are presented. The studied species are: Cameraria ohridella Deschka & Dimic 1986, Parectopa robiniella Clemens 1863, Phyllonorycter robiniella (Clemens 1859), Phyllonorycter issikii (Kumata 1963), Hyphantria cunea (Drury 1773), Obolodiplosis robiniae (Haldeman 1847), Leptoglossus occidentalis Heidemann 1910, Eopineus strobus (Hartig 1837), Megastigmus spermotrophus Wachtl 1893 and Harmonia axyridis Pallas 1773. The native range of each species, the first report and the present distribution in Europe and in Romania are discussed. The new records suggest that all the analysed species have established populations in our country and a more widespread distribution than that previously known. Some of them attain sometimes locally or zonally high population levels and are regarded as important pests. For the most species, new observations are necessary, both concerning their presence in the areas where they were not found so far, but also to assess the impact of insect populations on their hosts and on the recipient biocoenoses. A particular attention should be paid to the species H. axyridis, whose swarms invade the houses of the people during the autumn and could cause annoyance and possibly allergy. Citizen participation in observing and reporting of these new ”guests” is encouraged.
