We present a genome assembly from a female specimen of Scolitantides orion (Chequered Blue; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The assembly contains two haplotypes with total lengths of 525.32 megabases and 523.62 megabases. Most of haplotype 1 (99.85%) is scaffolded into 23 chromosomal pseudomolecules, including the Z sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.25 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
