Spider Mites (Tetranychidae)

This is the most common cause of fine webbing on Phalaenopsis orchids. These microscopic arachnids pierce plant cells to suck out sap, leaving behind characteristic silken webs, especially around the leaf axils and flower spikes.

Spider Mite Infestation (Aggravated by Low Humidity)

While still spider mites, the webbing often becomes more dense and visible when the environment is too dry. Phalaenopsis orchids thrive in high humidity; lack of moisture triggers a rapid reproductive cycle in mite populations.

Very Common

Thrips (Secondary Silk Production)

While thrips are primarily known for silver scarring on leaves, heavy infestations can sometimes cause debris and silken strands as they move through leaf crevices. They feed on the tender tissue of new orchid growth.

Common
