Two-Spotted Spider Mite Infestation

Spider mites are the primary culprit for fine webbing on Chrysanthemums, as they thrive in the warm, dry conditions common during summer. They pierce plant cells to feed, causing stippling and the production of silk webs to protect their colonies.

Tetranychus urticae (European Red Spider Mite)

Extreme Low Humidity / Environmental Stress

While webbing is biological, extreme lack of humidity can cause certain opportunistic mites to bloom rapidly. This stress weakens the plant's natural defenses, making the Chrysanthemum more susceptible to silk-producing pests.
