# The genome sequence of the hoverfly, Brachypalpoides lentus Meigen, 1822 (Diptera: Syrphidae)

## TL;DR

This paper presents the genome sequence of the hoverfly Brachypalpoides lentus, including detailed assemblies of its chromosomes and mitochondrial DNA.

## Contribution

The novel contribution is the first reference genome assembly for Brachypalpoides lentus, including sex chromosomes and mitochondrial DNA.

## Key findings

- The genome assembly includes two haplotypes with total lengths of 1,315.37 and 1,154.75 megabases.
- Haplotype 1 is scaffolded into 6 chromosomal pseudomolecules, including X and Y sex chromosomes.
- The mitochondrial genome is assembled with a length of 15.88 kilobases.

## Abstract

We present a genome assembly from an individual male
Brachypalpoides lentus (hoverfly; Arthropoda; Insecta; Diptera; Syrphidae). The assembly contains two haplotypes with total lengths of 1 315.37 megabases and 1 154.75 megabases. Most of haplotype 1 (95.66%) is scaffolded into 6 chromosomal pseudomolecules, including the X and Y sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.88 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.
