The genome sequence of the scarce swallowtail, Iphiclides podalirius

Abstract

The scarce swallowtail, Iphiclides podalirius (Linnaeus, 1758), is a species of butterfly in the family Papilionidae. Here we present a chromosome-level genome assembly for I. podalirius as well as gene and transposable element annotations. We estimate heterozygosity within different partitions of the genome and find a negative correlation between chromosome length and heterozygosity at fourfold-degenerate sites. This high quality genome assembly, the first for any species in the tribe Leptocircini, will be a valuable resource for population genomics in the genus Iphiclides and comparative genomics more generally.
