Solitary bees in the garden
At the end of April, I noticed a lot of solitary bees searching our fence and walls for openings, so quickly repurposed an old nest box to provide so accomodation for them on a south facing wall. An instant success! Within hours, bees of all sizes were exploring and using the box. Nearly all the cavities are now occupied.
