What Do Leafhoppers Eat?

All feed on plant sap

plant sap
Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Sap is distinct from latex, resin, or cell sap; it is a separate substance, separately produced, and with different components and functions.

. Leafhopper species feed on a wide variety of vascular plant species, including grasses, sedges, broad-leafed woody and herbaceous plants of many families, and conifers.

Do leafhoppers damage plants?

Are leafhoppers harmful?

Ecological Impact. Leafhoppers damage the plants they feed on. Their sucking mouth-parts deposit a toxic saliva secretion in the leaves and stems, causing white or yellow bumps to appear. Hopperburn is when the leaves turn yellow or brown from leafhopper damage, causing stunted growth or death of the plant.
