The meadow spittlebug, Philaenus spumarius (L.) (Hemiptera, Aphrophoridae) is a widespread insect species in the Holarctic region, exhibiting a dorsal colour balanced polymorphism. In the Azores the species is known from high elevations in Terceira and São Miguel islands. A sample of 235 individuals from Pico da Vara and Graminhais protected areas (São Miguel, Azores) (between 645 and 935 m a.s.l.), collected in 2000 and 2017, showed a remarkable high frequency of the melanic morphs flavicollis (FLA) and quadrimaculatus (QUA). In addition, a high frequency of melanics was observed in males. We explore the hypotheses for the origin of Azorean colonization and for the high proportion of melanism in the Azorean populations.
草地沫蝉,Philaenus spumarius (L.)(半翅目,沫蝉科)是一种在全北区广泛分布的昆虫物种,呈现出背部颜色平衡多态性。在亚速尔群岛,该物种见于特塞拉岛和圣米格尔岛的高海拔地区。2000年和2017年从皮科 - 达 - 瓦拉和格拉米奈斯保护区(圣米格尔岛,亚速尔群岛)(海拔645至935米)采集的235个个体样本显示,黑化形态黄颈型(FLA)和四斑型(QUA)的频率极高。此外,在雄性个体中也观察到高频率的黑化现象。我们探讨了亚速尔群岛种群的殖民起源以及黑化比例高的相关假说。
