The forewings are hairy (instead of scaly like a moths). They protect soft abdomen from predators and abrasion from coarse particles drifting in stream. Case-building larvae are the most diverse and abundant group, living in both running and still waters. As with most aquatic insects, the animal can appear different depending on its stage of development. The mechanical design of spider silks: from fibroin sequence to mechanical function. Some species are still known only as adults, while their larval stages have not been described yet. 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. Adults roost in shrubs and other plants during the day and fly at night. However, they lack the ability to breathe atmospheric oxygen that some other more tolerant insects have.

High Performance Marine and Terrestrial Bioadhesives and the Biomedical Applications They Have Inspired. Caddisfly larvae go through a number of molts before entering the pupal, or cocoon, stage. Their wings are covered with hairs instead of scales, as like in moths. Caddisflies are important members of the food web because they eat dead organic matter that has fallen onto or been washed into their habitat, and in some cases, help transport it to other habitats by carrying it along with silk threads spun from glandular hairs on their legs.
