Abstract
We present a genome assembly from an individual male Alsophila aescularia (the March moth; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 901.6 megabases in span. Most of the assembly is scaffolded into 14 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.67 kilobases in length. Gene annotation of this assembly on Ensembl identified 13,618 protein coding genes.
