Caddisfly Stone Case Nature Stream Macro Habitat

Weave caddisfly stone case nature stream macro habitat as a complete nature image prompt for a caddisfly larva case built from tiny stones in a shallow stream. Put pebble case, clear current, sand grains, and tiny aquatic plants at the center of the visual idea, then support the first read with individual stone pieces, water sparkle, small root fibers. Use filtered water light with crisp macro detail, a pebble gray, stream blue, and plant green palette, and a camera direction that will magnify the case at streambed level so the tiny construction remains understandable. The result should feel tiny, engineered, and natural, with believable natural proportions, readable depth, and enough texture for close inspection. Keep people, buildings, logos, captions, artificial props, and watermarks out of the frame.
