Spider Mites (Tetranychidae)

The presence of fine, silky webbing is a classic sign of a spider mite infestation. These tiny arachnids feed on the sap of Phalaenopsis leaves, causing stippling and eventual leaf yellowing as they deplete the plant's resources.

High Humidity with Poor Air Circulation

While Phalaenopsis orchids thrive in humidity, extremely high levels combined with stagnant air can create a microclimate that supports fungal growth or mimics web-like structures through condensation/mold filaments.

Thrips Infestation (Early Stage)

While thrips typically cause silvery streaks or deformed new growth, their feeding damage can sometimes be obscured by secondary fungal growth or fine silk-like secretions in extreme cases of high moisture.

Common
