Two-Spotted Spider Mite (Tetranychus urticae)

This is the most frequent cause of fine webbing on Hosta leaves, especially in hot, dry conditions. These arachnids pierce plant cells to suck out contents, leaving behind characteristic stippling and silk webs.

Very Common

Southern Yellow Stripe Mite

Common in warmer climates, these mites create fine silken webs that can bridge gaps between Hosta leaves. They cause yellowing stripes along the leaf veins which eventually lead to desiccation.

Edema (Physiological Disorder)

While not a direct producer of webs, the swelling of Hosta cells due to irregular watering can cause leaf cracking. This structural damage often traps dust and debris, which can mimic the appearance of fine webbing or residue.

Common

How to confirm: Look for small, blister-like bumps or corky patches on the leaf surface rather than moving organisms.
