Skeletonized Water Lily Pads: Aphids or Mites, Not Snails

Lily pads in a 500-gallon fishless pond are being eaten to the veins. The owner suspects snails or larvae, but the damage pattern points to chewing insects.

Real Culprits: Aphids or Spider Mites

• Aphids: Tiny, often green/black, cluster on undersides; leave sticky honeydew.
• Spider mites: Microscopic, red/brown; cause stippling and webbing.

Both have piercing/sucking mouthparts but can cause skeletonizing in heavy infestations. True chewing pests (caterpillars, beetles) are less common on lilies.

Safe Treatment

1. Identify: Check leaf undersides with a magnifier for tiny dots.
2. Hot sauce spray: 1 tsp hot sauce + 1 quart water + drop of dish soap. Spray pads thoroughly; repeats weekly.
3. Neem oil: Effective on both, safe for plants.
4. Beneficial insects: Ladybugs, lacewings control aphids naturally.

Since there are no fish, treatment options are broad. Avoid systemic insecticides that could harm future pond life.
