The genome sequence of the Red Sword-grass moth, Xylena vetusta (Hubner, 1813) (Lepidoptera: Noctuidae)

We present a genome assembly from an individual male Xylena vetusta (Red Sword-grass; Arthropoda; Insecta; Lepidoptera; Noctuidae). The assembly contains two haplotypes with total lengths of 611.09 megabases and 608.87 megabases. Most of haplotype 1 (99.67%) is scaffolded into 31 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 15.42 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland.
