The genome sequence of the Winter Shade, Tortricodes alternella [Denis & Schiffermüller], 1775.

We present a genome assembly from an individual male Tortricodes alternella (the Winter Shade; Arthropoda; None; Lepidoptera; Tortricidae). The genome sequence is 441.2 megabases in span. Most of the assembly is scaffolded into 22 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.73 kilobases in length. Gene annotation of this assembly on Ensembl identified 17,280 protein coding genes.
