系统发育信息有助于理解适应性性状的进化历史。在这里，我们提出了一个很好的解决系统发育假说Heliconius蝴蝶和相关属。我们用这棵树来研究三个性状的进化，花粉喂养，蛹交配行为和幼虫群居。根据线粒体基因细胞色素氧化酶I、细胞色素氧化酶II和16 SrRNA的部分序列，以及核基因延伸因子-1 α、无翅、无翅和无翅的片段（共3834 bp），推测了60个蝎蛉亚科种（占该亚族的86%）的系统发育关系。这些结果证实了以前的假设的基础上，序列数据显示，Heliconius是并系的，与Laparus doris和聂鲁达属于属内，表现出一个单一的起源花粉喂养，但与聂鲁达的性状的损失。然而，不同的基因在聂鲁达的位置上并不一致;因此，不能排除花粉喂养物种的单系性。也有一个高度支持的单系'蛹交配分支'表明蛹交配行为只进化了一次Heliconiina。此外，我们观察到至少有三个独立的起源幼虫群居从一个孤独的祖先，表明群居幼虫的行为后出现警告着色。(C)2007年，伦敦林奈学会。
Phylogenetic information is useful in understanding the evolutionary history of adaptive traits. Here, we present a well-resolved phylogenetic hypothesis for Heliconius butterflies and related genera. We use this tree to investigate the evolution of three traits, pollen feeding, pupal-mating behaviour and larval gregariousness. Phylogenetic relationships among 60 Heliconiina species (86% of the subtribe) were inferred from partial DNA sequences of the mitochondrial genes cytochrome oxidase I, cytochrome oxidase II and 16S rRNA, and fragments of the nuclear genes elongation factor-1 alpha, apterous, decapentaplegic and wingless (3834 bp in total). The results corroborate previous hypotheses based on sequence data in showing that Heliconius is paraphyletic, with Laparus doris and Neruda falling within the genus, demonstrating a single origin for pollen feeding but with a loss of the trait in Neruda. However, different genes are not congruent in their placement of Neruda; therefore, monophyly of the pollen feeding species cannot be ruled out. There is also a highly supported monophyletic 'pupal-mating clade' suggesting that pupal mating behaviour evolved only once in the Heliconiina. Additionally, we observed at least three independent origins for larval gregariousness from a solitary ancestor, showing that gregarious larval behaviour arose after warning coloration.
