## TL;DR

This paper presents the genome sequence of the Oriental Meadow Brown butterfly, including detailed haplotype and mitochondrial genome assemblies.

## Contribution

The study provides a high-quality genome assembly for Cercyonis lupina, including sex chromosomes and mitochondrial DNA.

## Key findings

- The genome assembly includes two haplotypes totaling 508.65 and 467.75 megabases.
- Haplotype 1 is scaffolded into 30 chromosomal pseudomolecules, including W and Z sex chromosomes.
- The mitochondrial genome is assembled with a length of 15.22 kilobases.

## Abstract

We present a genome assembly from a female specimen of
Cercyonis lupina (Oriental Meadow Brown; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 508.65 megabases and 467.75 megabases. Most of haplotype 1 (99.9%) is scaffolded into 30 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.22 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
