We present a genome assembly from a female specimen of Cyclophora albipunctata (the Birch Mocha; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence has a total length of 319.40 megabases. Most of the assembly is scaffolded into 32 chromosomal pseudomolecules, including the W and Z sex chromosomes. The mitochondrial genome has also been assembled and is 16.92 kilobases in length. Gene annotation of this assembly on Ensembl identified 16,542 protein-coding genes.
