Caddisflies

Stagnant or slow-moving freshwater environments, including ponds, lakes, and streams.

Larvae are generally omnivorous or detritivorous, feeding on decaying organic matter, algae, and small invertebrates.

Adult females deposit eggs in a protective gelatinous mass on vegetation or surfaces near water. Upon hatching, the larvae drop into the water and often construct protective cases from silk and debris.

They are harmless to humans and serve as a crucial food source for fish and birds, and are indicators of good water quality.
