The genome sequence of the Mottled Grey, Colostygia multistrigaria (Haworth, 1809) (Lepidoptera: Geometridae)

We present a genome assembly from an individual male <i>Colostygia multistrigaria</i> (Mottled Grey; Arthropoda; Insecta; Lepidoptera; Geometridae). The assembly contains two haplotypes with total lengths of 482.72 megabases and 504.67 megabases. Most of haplotype 1 (99.19%) is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 17.63 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
