Abstract
We present a genome assembly from an individual male Peribatodes rhomboidaria (the Willow Beauty; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 499.7 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 15.7 kilobases in length. Gene annotation of this assembly on Ensembl identified 18,486 protein coding genes.
