Two-Spotted Spider Mite Infestation

Spider mites are the most common cause of fine webbing on lilies. They thrive in hot, dry conditions and pierce the lily leaves to suck out chlorophyll, leading to stippling and eventually visible silken webs.

Very Common

warning

Extreme Low Humidity / Desiccation

While not a direct cause of webbing, extremely dry air can stress Lilium OT hybrids, causing them to become more susceptible to mite outbreaks and potentially creating a dusty, web-like appearance from debris sticking to sticky, stressed leaves.

Common
