Two-Spotted Spider Mites (Tetranychus urticae)

The presence of fine webbing is a classic sign of a spider mite infestation, which thrives in the warm, dry conditions often found with Anthuriums. These pests pierce plant cells to suck out sap, causing stippling and eventual leaf chlorosis.

Low Humidity causing Desiccation

In extremely dry environments, the edges of Anthurium leaves can become brittle and fray, which may superficially resemble fine webbing or silk. This is common when indoor humidity drops below the required 60% for this species.

How to confirm: Check if the 'webbing' is actually just frayed, dried-out leaf margins and monitor your hygrometer levels.

Broad Mites (Polyphagotarsonemus latus)

While they don't produce large webs, extreme infestations can cause silk-like threads and significant leaf distortion in Anthuriums. They primarily attack the new growth and tender undersides of the foliage.

Common
