We present a genome assembly from an individual female Scaeva pyrastri (the pied hoverfly; Arthropoda; Insecta; Diptera; Syrphidae). The genome sequence is 320 megabases in span. Most of the assembly is scaffolded into four chromosomal pseudomolecules, including the assembled X chromosome. The mitochondrial genome has also been assembled and is 17.3 kilobases in length. Gene annotation of this assembly on Ensembl identified 11,352 protein coding genes.
