The genome sequence of the Olive Skipper, Pyrgus serratulae (Rambur, 1839) (Lepidoptera: Hesperiidae)

<ns3:p> We present a genome assembly from a male specimen of <ns3:italic>Pyrgus serratulae</ns3:italic> (Olive Skipper; Arthropoda; Insecta; Lepidoptera; Hesperiidae). The assembly contains two haplotypes with total lengths of 718.44 megabases and 764.21 megabases. Most of haplotype 1 (99.4%) is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome. Most of haplotype 2 (93.51%) is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled, with a length of 15.42 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths. </ns3:p>
