What evidence is there that rose apids feed off rosebushes?

Evidence that rose aphids feed on rosebushes includes the presence of these small, soft-bodied insects clustered on the stems and undersides of leaves, where they pierce plant tissues to extract sap. Additionally, the resulting damage can manifest as curled or distorted leaves, and a sticky residue known as honeydew, which can attract other pests and lead to sooty mold growth. Observing these signs in conjunction with the identification of rose aphids confirms their feeding on rosebushes.
