# The genome sequence of the Grey Tortrix moth, Cnephasia stephensiana (Doubleday, 1850) (Lepidoptera: Tortricidae)

## TL;DR

This paper presents the genome sequence of the Grey Tortrix moth, including two haplotypes and a mitochondrial genome, as part of a larger project to sequence species in Britain and Ireland.

## Contribution

The paper provides a high-quality reference genome for Cnephasia stephensiana, including chromosomal pseudomolecules and a mitochondrial assembly.

## Key findings

- The genome assembly includes two haplotypes with lengths of 465.14 and 465.69 megabases.
- Haplotype 1 is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome.
- The mitochondrial genome is 16.63 kilobases long and has been assembled.

## Abstract

We present a genome assembly from an individual male
Cnephasia stephensiana (Grey Tortrix; Arthropoda; Insecta; Lepidoptera; Tortricidae). The assembly contains two haplotypes with total lengths of 465.14 megabases and 465.69 megabases. Most of haplotype 1 (99.5%) is scaffolded into 30 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 16.63 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.
