The genome sequence of the Geranium argus, Eumedonia eumedon (Esper, 1780) (Lepidoptera: Lycaenidae)

<ns3:p> We present a genome assembly from a female specimen of <ns3:italic>Eumedonia eumedon</ns3:italic> (Geranium Argus; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The assembly contains two haplotypes with total lengths of 551.86 megabases and 492.84 megabases. Most of haplotype 1 (99.86%) is scaffolded into 25 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.3 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths. </ns3:p>
