The complete mitochondrial genome and phylogenetic analysis of the European map butterfly Araschnia levana (Insecta: Lepidoptera: Nymphalidae)

Abstract

The European map butterfly Araschnia levana (Linnaeus, 1758) is a species showing extreme seasonal polyphenism. The complete 15,207 bp circular A. levana mitogenome consisting of 81.6% AT nucleotides, was assembled by Illumina genome skimming. It includes 22 tRNAs, 13 protein-coding genes, 2 rRNAs, and a control region in the typical butterfly gene order. Araschnia levana COX1 features an atypical CGA start codon and ATP6, COX1, COX2, ND1, ND3, and ND4 have incomplete stop codons completed by 3′A residues added to the mRNA. Phylogenetic reconstruction places A. levana as a basal lineage within tribe Nymphalini, consistent with previous phylogenetic hypotheses.
