Abstract
We present a genome assembly from an individual female Megachile leachella (the silvery leafcutter bee; Arthropoda; Insecta; Hymenoptera; Megachilidae). The genome sequence is 573.0 megabases in span. Most of the assembly is scaffolded into 16 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 21.04 kilobases in length.
