Two-Spotted Spider Mite Infestation

The fine webbing is a hallmark sign of spider mites, which thrive in the warm, dry conditions often experienced by OT Hybrids. These pests pierce the lily cells to suck out sap, leading to stippling and eventual leaf senescence.

Very Common

Tetranychus urticae (European Red Spider Mite)

Very Common

warning

High Humidity and Lack of Airflow (Secondary Webbing)

While not a direct cause of webbing, excessive moisture trapped in dense OT Hybrid foliage can encourage secondary fungal growth or allow existing mite populations to explode due to lack of environmental stress.

Common

How to confirm: Check if the soil surface remains damp for extended periods and if the plant is crowded by other vegetation.

2 Increase air circulation around the dense foliage by using a small fan or spacing plants further apart to reduce trapped moisture.

3 Prune away any heavily damaged or excessively dense foliage to improve airflow and reduce the humidity pockets that encourage secondary growth.
