Two-Spotted Spider Mite Infestation

The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Anthuriums. They pierce the plant cells to feed on sap, leading to stippling and eventual leaf drop.

Low Humidity (Environmental Stress)

While webbing is biological, extremely low humidity can stress Anthurium andraeanum foliage, making it easier for pests to colonize. This lack of moisture weakens the plant's natural cuticle barrier.

Broad Mite Infestation

While less likely to produce large webs than spider mites, broad mites can cause physiological distortions and silk-like secretions in high-density infestations. They are much smaller and harder to see with the naked eye.

Common
