1. Nutritional symbiosis between insects and microorganisms (bacteria and/or yeast‐like symbionts) that provide amino acids and vitamins which are lacking in the diet of host insects is widespread in nature. Auchenorrhyncha are usually host to two ancient bacterial symbionts – bacterium Sulcia (Bacteroidetes) and a betaproteobacterium – which, in some groups, were lost or replaced by other bacteria.

1. 昆虫和微生物（细菌和/或酵母样共生体）之间的营养共生在自然界中广泛存在，它们提供宿主昆虫饮食中缺乏的氨基酸和维生素。Auchenorrhyncha 通常是两种古老细菌共生体的宿主——细菌 Sulcia (Bacteroidetes) 和一种 betaproteobacterium——在某些群体中，它们已经消失或被其他细菌取代。
