成虫饮食是导致鳞翅目生活史变异的主要因素。特别是，来自成体喂养的氨基酸被怀疑对健康有重要贡献，但迄今为止只有少数物种能够证明这一点。在婆罗洲雨林群落的 13 个物种中，对氨基酸对蝴蝶饮食的影响进行了实验研究（使用没有交配机会的笼中雄性蝴蝶）。当在水、钠和糖溶液中添加氨基酸混合物时，四种物种的寿命显着延长。尽管六种粉蝶属物种中没有一个属于具有显着影响的类群，但没有发现氨基酸喂养影响的显着系统发育模式。对氨基酸有反应的物种往往是群落中最长寿的类群之一，这表明氨基酸是实现长寿命的关键变量。其余分类单元中不能排除较弱的影响或对其他适应性相关变量的影响。结果表明，成年氨基酸摄入可能并不是少数外来类群的罕见策略，但至少在非季节性热带地区，这是大量蝴蝶物种的常见生活史特征。
Adult diet is a major factor contributing to life history variation in the Lepidoptera. Amino acids derived from adult feeding, in particular, are suspected to be a major contribution to fitness, but this could be proven in only few species so far. Effects of amino acids in the diet of butterflies were experimentally investigated in 13 species from a Borneo rainforest community (using caged males without mating opportunity). Four species lived substantially longer when given a mix of amino acids additionally to water, sodium and sugar solutions. No significant phylogenetic pattern was found for effects of amino acid feeding, although none of six pierid species were among the taxa with significant effects. Species that do react to amino acids tend to be among the most long-lived taxa in the community, suggesting that amino acids are a key variable to attain long life spans. Weaker effects, or impacts on other fitness-related variables, cannot be excluded in the remaining taxa. Results indicate that adult amino acid intake may not be a rare strategy of few exotic taxa, but is, at least in non-seasonal tropical regions, a common life history trait in a substantial number of butterfly species.
