Abstract
We present a genome assembly from an individual male Epinotia nisella (the Grey Poplar Bell; Arthropoda; Insecta; Lepidoptera; Tortricidae). The genome sequence is 585.0 megabases in span. Most of the assembly is scaffolded into 28 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.44 kilobases in length. Gene annotation of this assembly on Ensembl identified 18,952 protein coding genes.
