Heortia vitessoides (Moore) is the most destructive defoliating pests in Aquilaria sinensis (Loureiro) Sprenger forests in Southern China. The complete sequences of mitochondria is reported: a circular molecule of 15,516 bp in size included 40.13% for A, 40.79% for T, 11.23% for C and 7.86% for G. There are 60 genes including 3 species with 12 protein-coding genes, 2 different species ribosomal RNA genes (S and L rRNA species), 46 transfer RNA genes (20 RNA species). H. vitessoides (Moore) and other 19 species belonging to lepidopteran were phylogenetic and analyzed by MEGA 6.06 with neighbor-joining methods. The mtDNA of H. vitessoides (Moore) were clustered in lepidopteran superfamilies.
