Do sucking pests leave visible damage on plants?

Sucking pests typically feed on the sap of plants, which can lead to symptoms that may not always manifest as evident physical damage such as large holes. Instead, they often cause clear discoloration and distortions in the foliage. These changes can include yellowing leaves, curling, and stunted growth, as the plant may be deprived of essential nutrients. While sucking pests do not usually create obvious holes like chewing pests, their feeding can still significantly affect the overall health and appearance of the plant, leading to damage that is more subtle and sometimes harder to detect until significant stress has occurred.
