四斑草螟（鳞翅目：草螟科）以韩国最著名的传统药物之一的白前（萝摩科）的块根为食。Glyphodes属植物在世界范围内约有130种，其线粒体基因组的完整性将有助于生物鉴定、地理学研究和多基因遗传学研究。长15，255 bp的G.四斑瓢虫基因组由37个典型基因和1个大的非编码区组成，具有鳞翅目昆虫的典型排列。在13个蛋白质编码基因（PCG）中，12个开始于昆虫线粒体PCG中发现的典型起始密码子，但COI基因起始于非典型CGA。基因组的一个值得注意的特征包括位于tRNA（Gln）和ND 2之间的51-bp长的非编码间隔序列的存在，其揭示了与相邻ND 2基因的高序列同源性（71.4%），表明该区域通过ND 2基因的部分重复而起源。
Glyphodes quadrimaculalis (Lepidoptera: Crambidae) feed on a root tuber of Cynanchum wilfordii (Asclepiadaceae), which is one of the most famous traditional medicines in Korea. The genus Glyphodes includes similar to 130 species distributed worldwide, so the complete mitochondrial genome (mitogenome) would be helpful for bio-identification, biogeographic studies and multigene-based phylogeny. The 15,255 bp long G. quadrimaculalis genome comprises 37 typical genes and 1 large non-coding region, with the typical arrangement found in Lepidoptera. Of the 13 protein coding genes (PCGs), 12 begin with typical start codons found in insect mitochondrial PCGs, but the COI gene starts with atypical CGA. One of the noteworthy features of the genome includes the presence of a 51-bp long non-coding space sequence located between tRNA(Gln) and ND2 that reveals high-sequence homology (71.4%) to the neighboring ND2 gene, indicating the origin of the region by partial duplication of the ND2 gene.
