Spider Mites (Tetranychidae)

The presence of fine webbing is a classic hallmark of spider mite infestations, which thrive in the warm, dry conditions often found with Phalaenopsis orchids. These pests pierce individual plant cells to feed on sap, causing stippling and eventual leaf chlorosis.

Low Humidity (Physiological Stress)

While not producing silk, extremely low humidity can cause the plant's micro-environment to become dusty or attract opportunistic pests. In some cases, dried nectar or sap from stress can trap airborne fibers, mimicking a webbed appearance.

Thrips Infestation (Secondary Effect)

While thrips primarily cause silvery streaks and scarring on Phalaenopsis leaves, their feeding damage can sometimes attract secondary pests or cause the plant to produce sticky honeydew that traps dust and debris into web-like structures.

Common

How to confirm: Inspect the crevices of the leaf axils and the base of the flower spikes for tiny, slender, elongated insects.
