We present a genome assembly from an individual female Craniophora ligustri (the Coronet; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 438 megabases in span. The whole assembly is scaffolded into 32 chromosomal pseudomolecules, including the Z and W sex chromosomes. The mitochondrial genome has also been assembled and is 15.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 12,834 protein coding genes.
