Abstract
We present a genome assembly from an individual male Eudonia truncicolella (the Peppered Grey; Arthropoda; Insecta; Lepidoptera; Crambidae). The genome sequence is 499.1 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 15.38 kilobases in length.
