# The genome sequence of the Short-tailed Blue, Cupido argiades (Pallas, 1771) (Lepidoptera: Lycaenidae)

## TL;DR

This paper presents the genome sequence of the Short-tailed Blue butterfly, including detailed assemblies of its chromosomes and mitochondrial DNA.

## Contribution

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

## Key findings

- The genome assembly includes two haplotypes with lengths of 445.87 and 384.46 megabases.
- Haplotype 1 is scaffolded into 25 chromosomal pseudomolecules, including W, Z1, and Z2 sex chromosomes.
- The mitochondrial genome is assembled with a length of 15.41 kilobases.

## Abstract

We present a genome assembly from a female specimen of
Cupido argiades (Short-tailed Blue; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The assembly contains two haplotypes with total lengths of 445.87 megabases and 384.46 megabases. Most of haplotype 1 (99.85%) is scaffolded into 25 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 15.41 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
