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. An insect order is a very large category, larger even than a family. But did not touch the rotala which is interesting. Most species of free-living caddisflies are very sensitive to pollution and level of dissolved oxygen. A more patient hunting approach is used by caddisflies in the genus Nyctiophylax.
