Although most crane fly larvae consume decaying plant materials and their associated microorganisms, all Libnotes species investigated so far are known to be xylophilous insects. Here we report the novel herbivorous feeding ecology of Libnotes puella. We found that L. puella larvae consumed the fruits or seeds of three unrelated plants, Mitrastemon yamamotoi (Mitrastemonaceae), Balanophora tobiracola (Balanophoraceae) and Barringtonia racemosa (Lecythidaceae). The larvae live within dense tubes formed by their feces fastened by their mucous excretions at the final stage, and they pupate within such tubes. This is the first detailed documentation of the fruit‐ and seed‐feeding habit of crane flies.

日本琉球群岛鹤蝇 Libnotes puella（双翅目：Limoniidae）的果实和种子取食习性

尽管大多数鹤蝇幼虫消耗腐烂的植物材料及其相关微生物，但迄今为止研究的所有 Libnotes 物种都已知是松材昆虫。在这里，我们报告了 Libnotes puella 的新型草食性饲养生态。我们发现 L. puella 幼虫消耗了三种无关植物的果实或种子，即 Mitrastemon yamamotoi (Mitrastemonaceae)、Balanophora tobiracola (Balanophoraceae) 和 Barringtonia racemosa (Lecythidaceae)。幼虫生活在由粪便在最后阶段被粘液排泄物固定而形成的致密管内，并在这些管内化蛹。这是关于鹤蝇食果和食种子习性的第一个详细记录。
