Abstract
We present a genome assembly from an individual female Cydalima perspectalis (the Box-tree Moth; Arthropoda; Insecta; Lepidoptera; Crambidae). The genome sequence is 483.7 megabases in span. Most of the assembly is scaffolded into 32 chromosomal pseudomolecules, including the Z and W sex chromosomes. The mitochondrial genome has also been assembled and is 15.25 kilobases in length.
