Signs you have a leaf-cutting bee
The female bee uses her jaws to cut a section of leaf from the foliage of plants, in gardens often roses, and then flies back to the nest site with the piece of leaf slung between her legs. In some cases many leaves on a plant can have sections taken out of them, however, this does not usually affect the health of the plant.
As well as in dry plant stems and cavities in wood, some species will use ‘bee hotels’ and nests are sometimes found in other places such as dry soil in plant pots and in wall cavities.
