Two-Spotted Spider Mite (Tetranychus urticae)

Spider mites thrive in the warm, dry conditions often experienced by Lilium hybrids. They pierce the lily leaf cells to feed on sap, leaving behind fine silk webbing as they create colonies on the undersides of foliage.

Very Common

How to confirm: Hold a white piece of paper underneath a leaf and tap it sharply to see if tiny moving dots fall onto the paper.

Common in many Lily varieties, these mites produce similar fine webbing, often accompanied by a reddish tint on the leaves as the mite population grows.

info

High Humidity/Microclimate Condensation

While rare, very high humidity combined with specific airflow patterns around dense lily foliage can sometimes trap fine fungal hyphae or dust in a web-like appearance.

Rare

How to confirm: Check if the 'webbing' disappears when you wipe it with a damp cloth versus if it is structurally attached to the leaf surface.

1 Improve airflow around the lily foliage by spacing plants further apart or using a small fan to prevent moisture from trapping on the leaves.

2 Gently wipe the leaves with a clean, damp cloth to remove any trapped dust or fungal hyphae caused by condensation.

3 Monitor the soil moisture levels to ensure the microclimate is not becoming overly saturated, which can exacerbate fungal growth.
