The genome sequence of an ichneumonid wasp, Ophion crassicornis Brock, 1982 (Hymenoptera: Ichneumonidae)

We present a genome assembly from an individual female Ophion crassicornis (ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence has a total length of 726.34 megabases. Most of the assembly (98.51%) is scaffolded into 13 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 38.03 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.
