Snail or Slug trail

Damp, moist environments, gardens, under leaves, logs, stones, basements, and other cool, secluded places.

The trail itself is not a diet, but snails and slugs feed on a variety of organic matter including decaying plant material, fungi, algae, and sometimes live plants.

Snails and slugs produce mucus to aid in locomotion, reduce friction, and protect them from desiccation. These trails dry into the visible patterns seen in the image. They are typically nocturnal or active during damp conditions to avoid drying out.

Risks: Can be pests in gardens, consuming ornamental and vegetable plants. Some species can carry parasites like lungworm (Angiostrongylus cantonensis) which can affect humans if ingested. Benefits: Decomposers, helping to break down organic matter and cycle nutrients back into the soil. Some species can be food sources for other animals.
