Orange-vented Mason Bee Osmia leaiana (Kirby, 1802)
One of two Osmia species which will occur in gardens. Osmia leaiana and Osmia caerulescens are both rarely recorded in Nottinghamshire, but this is purely down to the lack of widespread interest in our Hymenopterous fauna. Females nest in holes in existing holes or cavities in walls and trees, often utilising the exit holes of other invertebrates. Our thanks go to Duncan Lyon, for kindly allowing us to use his photograph of Osmia leaiana below, which was taken in Woodthorpe, Nottingham in late June 2019.
