How can one identify aphids on roses?

Identifying aphids on roses typically involves observing the sticky residue and warped leaves they cause. Aphids feed by piercing plant cells and sucking out sap, which can lead to the production of a sticky substance known as honeydew. This honeydew coats the leaves and often attracts other pests and diseases, creating a situation where the leaves can become shiny or appear wet. Additionally, the feeding activity of aphids can cause distortion or warping of the leaves as the plant tissue is damaged. This combination of visual cues—both the sticky residue and the physical deformation of the leaves—makes it clear that aphids are present. Recognizing these signs can be crucial for early intervention to protect the health and beauty of rose plants.
