The genome sequence of the Little Grey, Eudonia lacustrata (Panzer, 1804).

We present a genome assembly from an individual male Eudonia lacustrata (the Little Grey; Arthropoda; Insecta; Lepidoptera; Crambidae). The genome sequence is 699.5 megabases in span. Most of the assembly is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.29 kilobases in length. Gene annotation of this assembly on Ensembl identified 21,652 protein coding genes.
