描述了南威尔士两种叶肉食性叶蝉Lindbergina aurovittata(Douglas)和Edwardsiana rosae(L.)的生活史。第一代为常绿悬钩子和栎属交替生长，第二代为各种落叶阔叶树交替生长。对若虫取食偏好和成虫产卵行为的研究表明，两代若虫对老叶的喜好大于对幼叶的喜好，没有明显的种特异性。成虫的产卵偏好是有区别的，这种偏好会在交替的世代中规律地、完全地改变。玫瑰花也得到了类似的结果。寄主喜好和利用的季节性变化在蚜虫中是众所周知的，但以前在叶蝉中没有报道。
The life histories of 2 bivoltine mesophyll-feeding leafhoppers, Lindbergina aurovittata (Douglas) and Edwardsiana rosae (L.), in South Wales, are described. L. aurovittata alternates between evergreen Rubus and Quercus in the 1st generation and various deciduous broad-leaved trees in the 2nd F2. Experiments on nymphal food preferences and adult oviposition behavior show that nymphs of both generations prefer older to younger leaves with little species specificity. Adults are discriminating in oviposition preferences, which change regularly and completely in alternating generations. Similar results were obtained with E. rosae. Obligate seasonal changes in host preferences and utilization are well known among aphids, but previously not reported in leafhoppers.
