We present a genome assembly from an individual female Mythimna impura (smoky wainscot; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 949 megabases in span. The majority of the assembly (98.39\%) is scaffolded into 32 chromosomal pseudomolecules with the W and Z sex chromosomes assembled. The complete mitochondrial genome was also assembled and is 15.3 kilobases in length. Gene annotation of this assembly on Ensembl has identified 15,441 protein coding genes.
