Psyllids are oligophagous phytophagous insects with many specialist willow ( spp.) feeding species in two genera ( and ). We examine the patterns of distribution and co-occurrence of willow-feeding species at 42 willow sites across Europe forming a transect from Greece (lat. 38.8 °N) to arctic Norway (lat. 70.6 °N). The transect and sites have been described in previous papers. A total of 1245 individual psyllids were examined from 23 species of willow over the transect, representing 17 willow-feeding species (11 and 6 ). Numerous species were very widely distributed, with two species, (Foerster, 1848) and (Zetterstedt, 1840), occurring from Greece to Finland. Other widespread species (Romania to Finland) were (Foerster, 1848) and (Foerster, 1848). The mean number of psyllid species per site was 2.4 (1.3 , 1.1 ).
木虱是寡食性植食性昆虫，在两个属（和）中有许多专门取食柳树（柳属物种）的种类。我们研究了欧洲42个柳树分布地点的取食柳树的物种的分布和共存模式，这些地点形成了一条从希腊（北纬38.8°）到挪威北极地区（北纬70.6°）的样带。该样带和地点在以前的论文中已有描述。在整个样带上，从23种柳树中检查了总共1245只木虱个体，代表了17种取食柳树的物种（11种和6种）。许多物种分布非常广泛，有两个物种，（福斯特，1848年）和（泽特施泰特，1840年），从希腊到芬兰都有出现。其他广泛分布的物种（从罗马尼亚到芬兰）有（福斯特，1848年）和（福斯特，1848年）。每个地点木虱物种的平均数量为2.4种（1.3种，1.1种）。
