The genome sequence of the solitary wasp, <i>Nysson trimaculatus</i> (Rossi, 1790) (Hymenoptera: Crabronidae)

We present a genome assembly from an individual female <i>Nysson trimaculatus</i> (solitary wasp; Arthropoda; Insecta; Hymenoptera; Crabronidae). The assembly contains two haplotypes with total lengths of 301.31 megabases and 403.46 megabases. Most of haplotype 1 (86.44%) is scaffolded into 28 chromosomal pseudomolecules. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 25.2 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
