Data and code from: The evolution of proboscis length and feeding behavior in hawkmoths (Lepidoptera: Sphingidae)

Hawkmoths (Lepidoptera: Sphingidae) display some of the most extraordinary and iconic morphological adaptations. They are well known to have long proboscides, which have evolved to obtain nectar from flowers with deep tubes. Proboscides of some hawkmoths reach nearly five times their body length, but other species have mouthparts that have become completely non-functional. Adult nectar feeding is thought to have been gained and lost multiple times across the family, but has never been formally tested. Here, we examine this evolution of proboscis length and feeding behavior. We constructed a dated phylogeny of Sphingidae using a 537-locus anchored hybrid enrichment dataset, sampling 168 of the 205 sphingid genera (~82 %). We inferred a robust phylogeny and conducted ancestral state reconstructions of adult feeding behavior, revealing the evolution of feeding gains and losses. Our results show that adult feeding in hawkmoths first evolved around 44 million years ago, with the sphingid sub..., , # Data and code from: The evolution of proboscis length and feeding behavior in hawkmoths (Lepidoptera: Sphingidae)

## Description of the data and file structure

These data were used for building a time-calibrated phylogeny of hawkmoths (Lepidoptera: Sphingidae) and performing an ancestral state reconstruction to study the evolutionary history of proboscis length and feeding behavior.

天蛾（鳞翅目：天蛾科，Lepidoptera: Sphingidae）展现出一类极为独特且极具标志性的形态适应性特征。该类群以拥有修长的喙（proboscis，复数形式proboscides）而闻名，该结构演化用于从深管状花中获取花蜜。部分天蛾的喙长度可达其体长的近五倍，而另有一些类群的口器已完全丧失功能。学界普遍认为，成虫取食花蜜的习性在天蛾科中多次独立起源并丢失，但该假说从未经过正式的实证检验。本研究针对天蛾科的喙长度与取食行为演化展开探究。我们利用包含537个位点的锚定杂交富集（anchored hybrid enrichment, AHE）数据集，对205个天蛾属中的168个属（约占总数的82%）进行采样，构建了带有时间校准的天蛾科系统发育树。本研究重建得到了高置信度的系统发育树，并对成虫取食行为进行了祖先状态重建，揭示了取食习性起源与丢失的演化历程。研究结果显示，天蛾的成虫取食习性最早起源于约4400万年前，相关内容原文截断。
