Thrips feed by using their mouthparts to pierce plant cells and suck out their contents. Damaged plant cells collapse, resulting in deformed plant growth, flower deformation, or silvered patches and flecking on expanded leaves. If thrips feed on the surface of expanded leaves or petals, damage appears as small scars or silvered patches.
Greenish-black fecal specks are left by the thrips on plant surfaces as thrips feed. If thrips feed within developing buds, the damaged cells fail to grow as the leaf or flower expands, resulting in deformed leaves or flowers. Flower buds may abort in heavy infestations. Some plants develop a local dead or discolored spot where thrips eggs have been inserted into plant tissue.
