The genome sequence of Menetries' Clouded Yellow, <i>Colias thisoa</i> Ménétriès, 1832 (Lepidoptera: Pieridae)

We present a genome assembly from a female specimen of <i>Colias thisoa</i> (Menetries' Clouded Yellow; Arthropoda; Insecta; Lepidoptera; Pieridae). The assembly contains two haplotypes with total lengths of 398.28 megabases and 339.66 megabases. Most of haplotype 1 (99.82%) is scaffolded into 33 chromosomal pseudomolecules, including W and Z sex chromosomes and a supernumerary B chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.14 kilobases. Gene annotation of this assembly on Ensembl identified 14 651 protein-coding genes. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
