Treehoppers on Sunflowers: Harmless Visitors

Finding strange insects on the undersides of sunflower leaves can be alarming, but treehoppers are generally benign. These small, sap-feeding insects rarely cause significant damage to sunflowers or other garden plants.

Identification and Behavior

Treehoppers are close relatives of planthoppers, which often coat themselves in white, waxy filaments on hosts like hosta, azalea, and coneflower. Females may lay eggs in stems, but the impact is minimal.

Simple Management

If their presence bothers you, a strong blast from a garden hose will dislodge them. No chemical treatment is necessary.
