Extremely polyphagous. The species is regarded as a potential pest.


A Nearctic species, which was first collected in northern Italy in 2003 (D'Urso & Uliana, 2004). Up till now, the species is rapidly spreading through southern Europe: Italy, Switserland (Trivellone et al., 2015), Romania (Chireceanu, Teodoru, Gutue, Dumitru & Anastasiu, 2017), Slovenia (Seljak, 2018), Austria (Holzinger et al., 2020), Serbia (Šćiban & Kosovac, 2020), France (Pelozuelo et al., 2020) and Hungary (Kobor et al., 2021).
