Rhytidodus decimusquartus

Leafhopper Rhytidodus decimusquartus

Description

Rhytidodus decimusquartus is a leafhopper species found across Europe, known for feeding on a variety of deciduous trees and shrubs. It can affect a wide range of host plants, including Salix (willows), Populus (poplars), Betula (birches), and Alnus (alders). Rhytidodus decimusquartus is widely distributed throughout Europe, with its presence most prominent in forested areas, along rivers, and in woodlands where its preferred host trees grow.

Symptom

It attacks young leaves and shoots. Young leaves develop pale spots or blotches as a result of the leafhoppers sucking out sap. This feeding damage can lead to a stippled appearance, eventually causing the leaves to turn yellow or brown. Constant feeding can distort leaf growth, causing them to curl or crumple. Heavy infestations can weaken trees by reducing their ability to photosynthesize, leading to decreased growth, early leaf drop, and an overall decline in the tree's health. The leafhoppers excrete honeydew, which can coat the leaves and stems of trees. This sticky substance encourages the growth of sooty mold, a black fungal layer that further reduces the plant’s photosynthetic ability.
