Two-Spotted Spider Mite Infestation

The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Calla Lilies. These pests pierce plant cells to feed on sap, leading to stippling and eventual leaf senescence.

Very Common

Tetranychus urticae (European Red Spider Mite) outbreak due to Low Humidity

While technically a specific type of spider mite, these populations explode when the ambient humidity around the Zantedeschia foliage drops too low. The webbing acts as a protective micro-environment for the mites during dry spells.

Common

Thrips Infestation

While thrips usually cause silvery scarring rather than webbing, a heavy infestation can sometimes trigger secondary silk production by other small mites present in the disturbed foliage. This is less common but possible in greenhouse environments.

Common
