|There are half-circle cut outs on each of the leaves of my wild rose bush...what could this be?
|Cutter bees are harvesting parts of the leaves to build their nests. They'll stop soon and new leaves your rose develops will be just fine. Isn't nature interesting? The bees take only half the leaves. The remaining part of the rose leaf will still be able to manufacture nutrients to transport down to the roots and the cutter bees need the materials they need for nest building. Awesome!
