# The genome sequence of the Shy Cosmet Moth, Limnaecia phragmitella Stainton, 1851 (Lepidoptera: Cosmopterigidae)

## TL;DR

This paper presents the genome sequence of the Shy Cosmet Moth, including two haplotypes and a mitochondrial genome, as part of a broader project to sequence species in Britain and Ireland.

## Contribution

The novel contribution is the high-quality genome assembly of Limnaecia phragmitella, including chromosomal pseudomolecules and mitochondrial DNA.

## Key findings

- The genome assembly includes two haplotypes with lengths of 539.22 and 553.78 megabases.
- Haplotype 1 is scaffolded into 30 chromosomal pseudomolecules, including the Z sex chromosome.
- The mitochondrial genome is 15.26 kilobases long and was also assembled.

## Abstract

We present a genome assembly from an individual male
Limnaecia phragmitella (Shy Cosmet Moth; Arthropoda; Insecta; Lepidoptera; Cosmopterigidae). The assembly contains two haplotypes with total lengths of 539.22 megabases and 553.78 megabases. Most of haplotype 1 (98.9%) 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 15.26 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.
