The genome sequence of the European peacock butterfly, Aglais io (Linnaeus, 1758).

We present a genome assembly from an individual male Aglais io (also known as Inachis io and Nymphalis io ) (the European peacock; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The genome sequence is 384 megabases in span. The majority (99.91%) of the assembly is scaffolded into 31 chromosomal pseudomolecules, with the Z sex chromosome assembled. Gene annotation of this assembly on Ensembl has identified 11,420 protein coding genes.
