Armenia, Austria, Azerbaijan, Belarus, Belgium, Bulgaria, China, Czechia, Denmark, Estonia, Finland, France, Germany, Georgia, Greece, Hungary, Italy, Kazakhstan, Kyrgyzstan, Latvia, Moldova, Netherlands, Poland, Romania, Russia (European part), Slovakia, Slovenia, Spain, Switzerland, Tadzhikistan, Turkey, Turkmenistan, UK, Ukraine, Uzbekistan (Flor 1861 a; Schaefer 1949; Ramírez Gómez 1960; Wagner and Franz 1961; Dobreanu and Manolache 1962; Klimaszewski 1975; Lauterer 1977; Hodkinson and White 1979; Burckhardt 1988; Gegechkori and Loginova 1990; Ossiannilsson 1992; Burckhardt and Önuçar 1993; Conci et al. 1993; Lauterer 1993; Nokkala 1995; Baugnée et al. 2002; Burckhardt and Lauterer 2003; Ripka 2008; Serbina et al. 2015; Luo 2016; Bieman et al. 2019; Seljak 2020; Pramatarova et al. 2025); galls were reported from Luxemburg (Rapisarda et al. 2022). Host plant. Populus alba L., P. nigra L., P. tremula L., (Salicaceae), P. × generosa A. Henry (Hodkinson and White 1979; Nokkala 1995), confirmed with the presence of immatures. Galls were reported from P. × berolinensis K. Koch and P. × canadensis Moench (Ambrus 1958). On an internet site (https://bladmineerders.nl/parasites/animalia/arthropoda/insecta/hemiptera/sternorrhyncha/psylloidea/psyllidae/paurocephalinae/camarotoscena/camarotoscena-speciosa/) also following non-European species are cited though it is not stated where this information comes from and if the records are based on the presence of immatures: North American species: P. balsamifera L., P. deltoides W. Bartram ex Marshall; Asian species: P. lasiocarpa Oliv., P. simonii Carrière. Biology. Immatures in leaf roll galls. Probably bivoltine (Conci et al. 1993). In the south of France, adults are common in August (S. Grimaud, pers. obs.). The species occurs sometimes together with C. subrubescens (Flor 1861 b) (S. Grimaud, pers. obs.). Comment. The record from Mongolia (Klimaszewski 1973) refers to C. bianchii (Gegechkori and Loginova 1990). The registers from Iraq (Al-Maroof 1990; Mustafa et al. 2014) are doubtful and may concern other species.
