Mitochondrial genomes (mitogenomes) have been widely used for studies on phylogenetic relationships and molecular evolutionary biology. Here, the complete mitogenome sequence of Spilosoma lubricipedum (Noctuoidea: Erebidae: Arctiinae) was determined (total length 15,375 bp) and phylogenetic analyses S. lubricipedum were inferred from available noctuid sequence data. The mitogenome of S. lubricipedum was found to be highly A + T-biased (81.39%) and exhibited negative AT- and GC-skews. All 13 protein-coding genes (PCGs) were initiated by ATN codons, except for cox1 with CGA. All tRNAs exhibited typical clover-leaf secondary structures, except for trnS1. The gene order of the S. lubricipedum mitogenome was trnM-trnI-trnQ-nad2. The A + T-rich region of S. lubricipedum contained several conservative features common to noctuid insects. Phylogenetic analysis within Noctuoidea was carried out based on mitochondrial data. Results showed that S. lubricipedum belonged to Erebidae and the Noctuoidea insects could be divided into five well-supported families (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))).

线粒体基因组（mitogenomes）已被广泛用于系统发育关系和分子进化生物学的研究。在这里，确定了Spilosoma lubricipedum (Noctuoidea: Erebidae: Arctiinae)的完整有丝分裂基因组序列（总长度 15,375 bp），并从可用的 noctuid 序列数据推断了S. lubricipedum 的系统发育分析。的线粒体基因S. lubricipedum被发现是高度A + T-偏置（81.39％），并显示负AT-和GC-偏斜。除了带有 CGA 的cox1外，所有 13 个蛋白质编码基因 (PCG) 均由 ATN 密码子启动。除trnS1外，所有 tRNA 都表现出典型的三叶草二级结构。S. lubricipedum的基因顺序有丝分裂基因组是trnM-trnI-trnQ-nad2。S. lubricipedum富含 A + T 的区域包含几个夜蛾昆虫常见的保守特征。Noctuoidea 内的系统发育分析是基于线粒体数据进行的。结果表明，S. lubricipedum属于Erebidae，Noctuoidea昆虫可分为5个支持良好的科（Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))）。
