The genome sequence of the Mountain Clouded Yellow, <i>Colias phicomone</i> (Esper, 1780) (Lepidoptera: Pieridae)

We present a genome assembly from a female specimen of <i>Colias phicomone</i> (Mountain Clouded Yellow; Arthropoda; Insecta; Lepidoptera; Pieridae). The assembly contains two haplotypes with total lengths of 420.60 megabases and 355.84 megabases. Most of haplotype 1 (99.03%) is scaffolded into 31 chromosomal pseudomolecules, including the W, Z ₁, and Z ₂ sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.15 kilobases.
