Rose : Leafcutting bees
(revision date: 4/23/2014)


Biology
Leafcutting bees remove smooth circular or semi-circular notches from the edges of leaves of roses and other plants. The leaf pieces are used by the bees to create protective cells for raising their young. Leafcutting bees are important pollinators and seldom do major harm to plants.
Management Options


Non-Chemical Management
  • Provide proper culture for plants. Healthy plants can easily tolerate some damage by leafcutting bees.
  • Avoid use of pesticides which will harm these beneficial insects.
Select non-chemical management options as your first choice!
