常见的黄蝴蝶Eurema hecabe广泛分布于东亚，由于其众多的地理和季节性翅膀颜色模式，它是分类学家最繁重的物种之一。此外，在本种中，在日本温带地区出现的具有黄色翅缘的个体（Y型）被证明与在日本亚热带地区和东亚各地广泛出现的其他个体（B型）在生物学上不同。为了揭示这两个类型内和之间的遗传变异，共50个蝴蝶收集在东亚18个地理位置的3个线粒体区域：细胞色素氧化酶亚基I（COI），细胞色素氧化酶亚基III（COIII）和NADH脱氢酶亚基5（ND 5）的核苷酸序列变异进行了检查。此外，还检查了它们的内共生细菌Wolbachia的感染状况。3个线粒体序列一致表明：（i）Y型和B型高度分化;（ii）B型内的核苷酸变异非常小，尽管样本来自广泛的地理范围;（iii）线粒体DNA单倍型与沃尔巴克氏体感染状态之间存在弱关联。
The common yellow butterflyEurema hecabeis widely distributed in East Asia, and is one of the most burdensome species for taxonomists due to the numerous geographic and seasonal wing colour patterns. Moreover, within this species, individuals with a yellow wing fringe that occur in temperate regions of Japan (Y type) proved to be biologically different from others that occur widely in subtropical regions of Japan and all over East Asia (B type). To unveil the genetic variation within and between the two types, a total of 50 butterflies collected at 18 geographic localities in East Asia were examined for nucleotide sequence variation of three mitochondrial regions: cytochromecoxidase subunit I (COI), cytochromecoxidase subunit III (COIII) and NADH dehydrogenase subunit 5 (ND5). In addition, they were also examined for infection status with the endosymbiotic bacteriaWolbachia. The three mitochondrial sequences consistently showed that (i) Y type and B type were highly divergent, (ii) nucleotide variation within B type was very small although sampled from a geographically wide range, and (iii) a weak association existed between mitochondrial DNA haplotypes andWolbachiainfection status.
