Caddisfly Larva Case

Lakes, rivers, and streams with clean, oxygenated water

Depending on the species, they can be shredders of organic debris, filter-feeders of microscopic particles, or predators of small invertebrates.

The larvae construct protective cases from silk and available materials like sand, pebbles, or vegetable matter. They are often used as indicator species for water quality.

Harmless to humans; ecosystem benefit as a critical food source for fish and a key indicator of high water quality and low pollution levels.
