Tetranychus urticae (European Red Spider Mite)

This specific mite species is highly prevalent in greenhouse-grown Zantedeschia. The webbing acts as a protective microclimate for the mites, often accompanied by fine stippling (light-colored dots) on the variegated foliage.

warning

Low Humidity Stress

While not a direct cause of webbing, extremely low humidity can stress the Zantedeschia Captain Fresco, making its foliage more susceptible to mite attacks and causing the plant's natural silk-producing defense mechanisms (or incidental dust/debris) to become visible.
