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. |
