Egg deposition within plants is one of the most widely distributed and ancient behaviors in Odonata. The resulting clutch consists of eggs placed in peculiar pattern that can be a characteristic for certain groups of Odonata. Despite their importance for paleontological and evolutionary research, data on egg-clutch positioning are missing or insufficient for most species. Here, patterning of egg clutches in Lestes virens was measured and described in detail for the first time. The female usually produces a linear row of single eggs directed at an angle rightward or leftward to the longitudinal axis of plant substrate. Less often eggs are arranged in egg-sets consisting of up to 4 eggs. Apparently, the female insect follows the rigid behavior stereotypes during oviposition and is unable to easily switch to the alternate stereotypical behavior of single egg deposition or production of multiegg sets. Based on a literature review and original data, egg clutch patterning of European Lestidae is overlaid on preexisting phylogenies. The resulting evolutionary scenario of egg-clutch patterning can be considered in the framework of egg-laying behavior in Lestidae.
在植物体内产卵是蜻蜓目昆虫中分布最广泛且最古老的行为之一。所产的一窝卵以独特的模式排列，这可能是某些蜻蜓目昆虫群体的一个特征。尽管它们对古生物学和进化研究很重要，但大多数物种的一窝卵的定位数据缺失或不足。在此，首次详细测量并描述了绿纹晏蜓一窝卵的排列模式。雌性通常产下一排单个的卵，这些卵相对于植物基质的纵轴向右或向左呈一定角度排列。较少情况下，卵会排列成由多达4个卵组成的卵群。显然，雌性昆虫在产卵时遵循严格的行为模式，无法轻易切换到单个卵沉积或多卵群产生的交替模式行为。基于文献综述和原始数据，欧洲晏蜓科昆虫一窝卵的排列模式被叠加在已有的系统发育树上。由此产生的一窝卵排列模式的进化情景可以在晏蜓科昆虫产卵行为的框架内进行考量。
