[CDATA[ Predation and Parasitism Caddisfly larvae represent an important ecological component of nutrient processing and energy flow in lakes and rivers and provide a food source for a variety of aquatic predators, such as trout and other fish (Resh and Rosenberg, 1984; Johansson, 1991; Wiggins, 1996a).

"They came to this underwater adhesion solution completely independently," showing that it repeatedly evolved because of its value in helping the creatures live and thrive, Stewart says. He says the ability to make adhesives underwater now has been identified in four phyla - major categories of living organisms - that include caddisflies, sandcastle worms, mussels and sea cucumbers. And they have even been encouraged in aquariums to fashion their temporary protective cases with precious stones to create unique and intricate pieces of jewellery. The vegetation at the bottom of my pond stirred, and three small clumps sprouted legs and began creeping up the side.

WebThe caddisfly lives only a short time as an adult but may spend several years as a larva. Stewart's study included detailed analysis of the chemistry and structure of the caddisfly silk, showing how it is similar to what silkworm moths produce for use in textiles and even to spider web silk, but with adaptations that make it work underwater.

Brachycentrus echo, the species Stewart studied, is one of the casemakers, which build their case and then drag it along with them underwater as they forage for food.
