We present a genome assembly from a female specimen of Eumedonia eumedon (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.
