Project description:We present a genome assembly from an individual male Amphipoea lucens (the Large Ear; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 647.7 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the assembled Z sex chromosome. The mitochondrial genome has also been assembled and is 15.3 kilobases in length.
