# The genome sequence of the Chalk Yellow-face Bee, Hylaeus dilatatus (Kirby, 1802) (Hymenoptera: Colletidae)

## TL;DR

This paper presents the genome sequence of the Chalk Yellow-face Bee, part of a project to sequence species in Britain and Ireland.

## Contribution

The study provides a high-quality genome assembly for Hylaeus dilatatus, including two haplotypes and the mitochondrial genome.

## Key findings

- The genome assembly includes two haplotypes with lengths of 307.38 and 314.32 megabases.
- Most of each haplotype is scaffolded into 12 chromosomal pseudomolecules.
- The mitochondrial genome is 17.78 kilobases long.

## Abstract

We present a genome assembly from an individual female
Hylaeus dilatatus (Chalk Yellow-face Bee; Arthropoda; Insecta; Hymenoptera; Colletidae). The assembly contains two haplotypes with total lengths of 307.38 megabases and 314.32 megabases. Most of haplotype 1 (82.9%) is scaffolded into 12 chromosomal pseudomolecules. Most of haplotype 2 (73.52%) is scaffolded into 12 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 17.78 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.
