My husband drilled holes in a log of wood and hung it on the fence hoping that It would attract wildlife. We were delighted to see the Leaf cutter bee who has now filled 16 holes in a short period of time.. it is fascinating to watch.
For those interested I have added a link. https://www.rhs.org.uk/biodiversity/leaf-cutting-bees
Thanks for the link and the information. I am going to have to check and see if there are any in my yard. Spectacular photo and aren’t you the nicest people to help in their procreation?
