Abstract
We present a genome assembly from an individual male Campaea margaritaria (the Light Emerald; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 335.2 megabases in span. The whole assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.9 kilobases in length. Gene annotation of this assembly on Ensembl identified 16,403 protein coding genes.
