The genome sequence of the Heart Moth, Dicycla oo (Linnaeus 1758).

We present a genome assembly from an individual female Dicycla oo (the Heart Moth; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 936.7 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.29 kilobases in length. Gene annotation of this assembly on Ensembl identified 19,564 protein coding genes.
