Abstract
We present a genome assembly from an individual female Pollenia labialis (the dark-based cluster fly; Arthropoda; Insecta; Diptera; Polleniidae). The genome sequence is 908.0 megabases in span. Most of the assembly is scaffolded into 6 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 18.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 29,755 protein coding genes.
