Two-Spotted Spider Mite (Tetranychus urticae)

These microscopic arachnids thrive in hot, dry conditions and pierce the lily's leaf cells to suck out nutrients, leaving behind characteristic fine silk webbing. This is the most frequent cause of webbing on Lilium LA hybrids during summer months.

Very Common

European Red Spider Mite (Panonychus citri)

Similar to the two-spotted variety, these mites create fine webs on the undersides of foliage. They are particularly common in lilies grown in warmer climates and can cause the leaves to turn bronze or yellow.

Common

Fall Webworm (Hyphantria cunea)

While more common on deciduous trees, larvae can occasionally migrate to large lily leaves, spinning dense silk nests to protect themselves while feeding. Unlike spider mites, you will see distinct caterpillars within the webbing.

Common

How to confirm: Look for larger, caterpillar-like larvae moving within the silk structures rather than microscopic dots.
