lyen, homokbuckás területen, buckaközökben Cenkov közelében. Magyarországon is hasonló lelőhelyeken fogtam a fajt. Ez az előfordulás különbözik az Európa északi részén tapasztálhatótól és reliktum jellegűnek mondhatjuk. A faj Szlovákiában is és Magyarországon is kétnemzedékes, mint a többi füzeken élő Cacopsylla faj is. Miután a fajnak a Kárpát-medencében nagy populációi élnek, elterjedését boreomeridionálisnak nevezhetjük, ugyanúgy, mint tápnövényéét. Magyarországon a fajt az azonos tápnövényü Bactericera versicolor (Löw) levélbolhával együtt fogtam. A magyarországi példányok adatai: Fülöpháza, homokbuckás, buckaköz, 160 m, Salix repens rosmarinifolia, 1987. VII. 13. ; Bugac, borókás, 160 m, Salix repens rosmarinifolia, 1987. VII. 13., mindkét helyen számos himet és nőstényt gyűjtöttem. Cacopsylla parvipennis was previously considered to be a boreomontane species mainly occurring in northern Europe, largely in Scandinavia and around the Baltic Sea. It has been reported from Norway, Sweden, Finland, the Netherlands, Denmark, the German Democratic Republic, Poland, in the European part of the USSR from its northern and central part; it has even been quoted from Austria. The most southern occurrence of the species has been recorded in the southernmost part of Slovakia, viz., in the Cenkov State Nature Reserve in the Danube Lowland of the Carpathian Basin (Lauterer, 1965). According to the available data, this psyllid is monophagous on Salix repens, mostly on its ssp. rosmarinifolia. This willow species is of boreomeridional distribution, and the psyllid obviously follows this distribution, as noted by the author mentioned above. However, the species has not been found in numerous small, scattered localities of this willow in the coline, submontane and montane zones of Czechoslovakia, including an extensive area grown with it near Slezsky Kocov not far from Bruntál in northern Moravia. At Cenkov, Czechoslovakia, the species inhabits similar localities as in Hungary: in depressions between dunes of aeolian sands in extreme xerothermophilic conditions, with a relatively high water table, accessible to the host plant in the depressions. The occurrence of the species in such places is of a relict character and the habitat differs from those of the natural occurrence of the species in the northern part of Europe. These microclimatic and hydrological conditions and adaptation correspond in part to those prevailing in peat bogs of the mountain type. Under the conditions of Hungary and southern Slovakia, the species is apparently bivoltine like the remaining salicicolous Cacopsylla spp. Older adult individuals of the first generation, observed in Hungary, were pale testaceous and their wings had a feeble infumation in their apical parts. Young adults of the 2nd generation, collected by I. Vavrinová and L. Pospisilová at Cenkov in 1964, were bright green in colour (Lauterer, 1965). With regard to the finding of rich populations of the species in the Carpathian basin in xerothermophilic habitats, the distribution of the species should be evaluated as boreomeridional, the same as that of its host plant. In Hungary the species occurred along with Bactericera versicolor (Low), which, according to Dobreanu et Manolache (1962*, has the same host plant and whose observation I can confirm.
