Caddisfly Larva (in Case)

Freshwater environments such as streams, rivers, lakes, and ponds.

Mostly detritivorous, feeding on decaying organic matter, algae, and sometimes small insects.

Larvae construct protective cases using silk mixed with environmental materials like sand, pebbles, or twigs. They undergo complete metamorphosis into winged adults.

Harmless to humans; vital ecosystem indicators of water quality and a primary food source for fish.
