Why does your Lilium martagon have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These microscopic arachnids thrive in the warm, dry conditions often experienced by Lilium martagon during summer. They pierce plant cells to suck out chlorophyll, resulting in characteristic fine silken webs and stippling on the foliage.
Commonly found on Liliaceae species, these mites create much finer, less visible webbing than the two-spotted variety. They cause a gradual bronzing of the lily leaves as they deplete the plant's nutrient reserves.
While more common in woody plants, certain moth larvae can create dense silk nests on lily foliage. This webbing is much thicker and more structural than mite webbing and is accompanied by visible caterpillars.
