Abstract
We present a genome assembly from an individual male Hedya salicella (the White-backed Marble; Arthropoda; Insecta; Lepidoptera; Tortricidae). The genome sequence is 742.3 megabases in span. Most of the assembly is scaffolded into 25 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 11,961 protein coding genes.
