Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by hybrid lilies, feeding on the underside of leaves and secreting silk that forms characteristic fine webbing. This piercing-sucking habit causes stippling (tiny white dots) on the Lilium Minou foliage.

Very Common

Extreme Low Humidity (Environmental Stress)

While not a direct cause of webbing, extremely dry air can trigger dormant mite populations to become active and produce more silk as a protective microclimate for their eggs.

Common
