Two-Spotted Spider Mite (Tetranychus urticae)

This is the most common cause of fine webbing on Oriental Lilies. These arachnids thrive in hot, dry conditions and pierce lily cells to feed, leaving behind characteristic silk webs and stippled patterns on the foliage.

High Humidity/Fungal Micromycetes

In extremely high humidity with stagnant air, certain fungal species or molds can create a fine, web-like mycelial growth on the surface of lily petals or leaves.

Common
