We present a genome assembly from an individual female Emmelina monodactyla (the Common Plume; Arthropoda; Insecta; Lepidoptera; Pterophoridae). The genome sequence is 312 megabases in span. Most of the assembly is scaffolded into 30 chromosomal pseudomolecules, including the assembled W and Z sex chromosomes. The mitochondrial genome has also been assembled and is 15.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 13,451 protein coding genes.
