It's a moth! It's a butterfly! It's the complete mitochondrial genome of the American moth-butterfly (Warren, 1897) (Insecta: Lepidoptera: Hedylidae)!

The taxonomic placement of the moth-butterfly, (Warren 1897) (Lepidoptera: Hedylidae), has been controversial. The 15,344 bp complete circular mitogenome, assembled by genome skimming, consists of 81.7% AT nucleotides, 22 tRNAs, 13 protein-coding genes, 2 rRNAs and a control region in the typical butterfly gene order. features an atypical CGA start codon while and exhibit incomplete stop codons completed by the post-transcriptional addition of 3' A residues. Phylogenetic reconstruction places as sister to the skippers (Hesperiidae), which is consistent with several recent phylogenetic analyses.
