Was recorded as new to Britain in 2001 when Ian Cross discovered specimens at Langton Matravers in Dorset. Since then, the bee has spread across much of southern England (as far north as Shropshire, Staffordshire & Norfolk) and into south Wales. It is now extremely plentiful in some coastal localities, and increasingly, inland. Peak activity matches the flowering period of its key pollen forage plant, Ivy (Hedera helix), and the species is on the wing from early September until early November. This makes it the last solitary bee species to emerge each year. BWARS has been mapping the spread since its discovery in Britain 15 years ago.
