The genome sequence of the Dark Spectacle, Abrostola triplasia (Linnaeus, 1758).

We present a genome assembly from an individual male Abrostola triplasia (the Dark Spectacle; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 362.7 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.34 kilobases in length. Gene annotation of this assembly on Ensembl identified 11,532 protein coding genes.
