They find shallow grooves in a stream rocks, and roof them over with stretched silk. A caddisfly (or caddis fly) is any insect in the order Trichoptera. The amphoteric nature of the silk proteins could contribute to silk fiber assembly through electrostatic association of phosphorylated blocks with arginine-rich blocks.

The constructions are spliced together and glued down to the substrate by a silken thread. The larva attaches one end of a silk strand to an object and pulls it underwater where it deposits its sifting material, then ties off the other end to a rock or other anchorage so that when the caddisfly swims back up for air, any loose particles are left behind on the now-weighted silk line. 2021 Mar 25;12(4):281. doi: 10.3390/insects12040281.

The larvae are a link in the aquatic food chain, bridging the gap between the various organic matterials they eat, and the fish that eat them. Most species of free-living caddisflies are very sensitive to pollution and level of dissolved oxygen. The caddisfly larva lives underwater, and gathers bits of sand, gravel or other small particles to build a protective case for itself out of silk secreted from glands near the rear end. Consider the caddisflies of the family Rhyacophilidae. Caddisfly larvae have elongated bodies resembling caterpillars of moths and butterflies (similarity as between adults).
