The complete mitochondrial genome (mitogenome) of Junonia orithya Linnaeus (Lepidoptera: Nymphalidae: Nymphalinae) is determined to be 15,214 bp in length, including 37 typical mitochondrial genes and an AT-rich region. Its gene order and orientation are identical to those of other butterfly species. All PCGs are initiated by typical ATN codons, except for cox1 gene which is started by CGA codon. Nine genes use complete termination codon (TAA), whereas the cox1. cox2. nad1 and nad4 genes end with single T. Except for trnS1(AGN), all tRNA genes display typical secondary cloverleaf structures as those of other insects. The 331 bp long AT-rich region contains several features common to the other lepidopterans, such as the ATAGA motif followed by a 18 bp poly-T stretch, two microsatellite-like (TA)9 elements, a 5 bp poly-A stretch immediately upstream of trnM gene.
