Abstract In this study, the complete mitochondrial genome of Hydrelia parvulata (Staudinger, 1897) was firstly sequenced by high-throughput sequencing. As a circular DNA molecule, it is 15,407 bp in length (GenBank accession number: MN962739), which consists of 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and an AT-rich region. The nucleotide composition is A (39.8%), C (11.6%), G (8.2%), and T (40.4%). Based on the sequences of complete mitogenome from 10 geometrid species as ingroups and 3 bomby...
