The leg regeneration capabilities of damselflies are understudied. Here we present the first data of regenerated limbs across a genus of damselfly based on adult specimens collected in the field to illustrate the prevalence of limb loss among nymphs. We show that this phenomenon is much more prevalent than previously thought, as 42 percent of individuals were found with regenerated limbs. Furthermore, we test for patterns within these data to begin to unravel the potential causes of limb loss in nymphal damselflies, showing that intrinsic factors such as sex and species cannot explain the patterns of limb loss pointing to environmental factors as the probable cause. We argue that Odonata limb regeneration provides a potentially unique perspective into the nymphal stage of these organisms.

研究了豆娘的腿再生能力。在这里，我们根据田间收集的成年标本介绍了豆娘属中再生的四肢的第一批数据，以说明若虫中四肢丧失的普遍性。我们表明，这种现象比以前认为的要普遍得多，因为发现42％的人患有再生肢体。此外，我们测试了这些数据中的模式，以开始揭示若虫豆娘肢体丢失的潜在原因，表明内在因素（例如性别和物种）无法解释将环境因素作为可能原因的肢体丢失模式。我们认为，Odonata肢体再生为这些生物的若虫阶段提供了潜在的独特视角。
