Leaf Cutter Bees on Roses: Cosmetic Damage, No Harm Done

The Culprit

Neat, curved or spiral cuts on rose leaves are the signature of leaf cutter bees. They use the leaf pieces to line their nest cells.

Beneficial Insects

Leaf cutter bees are important native pollinators. The damage is purely cosmetic and does not harm the plant's health or flowering.

Management (If Desired)

If "perfect" foliage is required, use floating row covers during peak bee activity. Otherwise, enjoy the pollination benefits and tolerate the minor leaf art.
