Two-Spotted Spider Mite (Tetranychus urticae)

Spider mites thrive in the warm, dry conditions often found around Oriental lilies. They pierce individual plant cells to feed on sap, and as the population grows, they produce characteristic fine silken webbing across the leaves and flower buds.

Very Common

European Red Mite (Panonychus citri)

While similar to two-spotted mites, these red mites specifically target lilies in warmer climates. They create much finer, less visible webbing that can cause the lily foliage to take on a bronzed or dusty appearance.

Common

How to confirm: Inspect the undersides of the leaves for tiny, moving reddish-orange specks.

High Humidity/Microclimate Mold

In extremely dense lily beds with poor airflow, fine fungal mycelium can sometimes be mistaken for spider mite webbing. This occurs when moisture is trapped between the large, overlapping leaves of 'Medusa' lilies.

Common

How to confirm: Check if the 'webbing' disappears when wiped with a damp cloth or if it appears more as a fuzzy coating than a structured web.

1 Improve airflow around the lily bed by thinning out dense foliage or spacing plants further apart to prevent moisture from being trapped between leaves.
2 Apply an organic fungicide to treat the fungal mycelium and prevent the spread of mold within the microclimate.

3 Monitor soil moisture levels to ensure the base of the plant is not staying excessively wet, which can contribute to high humidity at the leaf level.
