Abstract
We present a genome assembly from an individual female Nothochrysa capitata (a black lacewing; Arthropoda; Insecta; Neuroptera; Chrysopidae). The assembly contains two haplotypes with total lengths of 688.43 megabases and 587.48 megabases. Most of haplotype 1 (78.72%) is scaffolded into 8 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 16.43 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.
