The genome sequence of the Eastern Rock Grayling, Hipparchia syriaca (Staudinger, 1871) (Lepidoptera: Nymphalidae)

<ns3:p> We present a genome assembly from a female specimen of <ns3:italic>Hipparchia syriaca</ns3:italic> (Eastern Rock Grayling; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 393.56 megabases and 365.79 megabases. Most of haplotype 1 (99.87%) is scaffolded into 30 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 15.47 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths. </ns3:p>
