Riffles: An area of stream characterized by shallow depths with fast, turbulent water. Caddisflies, or Trichoptera, are an order of aquatic insects known for the case and retreat-making behavior of the larval stage. Caddisflies, inconspicuous brown to gray insects, are the ecologically diverse and important group of insects. Larvae are important in nutrient cycling and energy flow in aquatic ecosystems. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. They are found in lakes and rivers around the world. Caddisflies are an important insect to the fly fisherman who will use many variations of artificial flies to mimic caddisfly larvae and adults to effectively lure and catch trout. benthic macroinvertebrate by exploring the life cycle, feeding habitats, interesting facts and its role in the food chain. Flies vs. Caddisflies Flies from the Diptera order have only one pair of wings, while caddisflies have two pair of wings. The type of materials used for caddisfly casings varies from species to species. Trichoptera, or caddisflies, comprise the most diverse insect order whose members are exclusively aquatic. Only aquatic Diptera outnumber them in species and ecological diversity. Adults of a particular species emerge from the water at about the same time, sometimes forming clouds of insects over the water. Caddisfly larvae are an important part of stream ecosystems, where they help control algae populations and provide food for fish and other creatures. Caddisflies are important insects in freshwater ecosystems, where they reproduce in streams, ponds, and lakes, serving as food for a wide variety of aquatic animals, especially fish. This explains why the name “caddisfly” comprises such a large group! Many anglers use a technique called fly fishing where they use specialized lures called flies to imitate the macroinvertebrates found in the stream (Figure 7).
