There is great diversity among American caddisflies, and naturally they can inhabit different habitats. Caddisfly life cycle is a form of incomplete metamorphosis. Dont worry though; these insects are too light for humans to feel them crawling on their skin. The larva attaches itself to some underwater object and begins secreting its outermost layer an opaque white casing that is called the exuvia. A new fly then emerges from this casing and climbs out of the water. Caddisflies undergo complete metamorphosis. Abdomen terminates with a pair of prolegs equipped with claws. The forewings are hairy (instead of scaly like a moths). The larvae collects whatever material it can to form its protective case, bonding the various materials together with silk that it excretes from its salivary glands near its mouth. While most caddisflies are considered sensitive to environmental stress, some caddisflies are less sensitive. They then emerge from the cocoon, float to the water's surface or the shore, and finish their transformation to an adult, terrestrial insect. A caddisfly larva eventually pupates, sealing off the tube as it develops into an adult fly and then hatches. How can I put sand into a tank that already has water and fish in it? Most species of free-living caddisflies are very sensitive to pollution and level of dissolved oxygen. Most species produce one generation per year. Larvae of some species move under the rocks, where they build solid shelters of sand and stones to protect the transforming pupae. Net-spinning larvae are common and abundant in running waters of streams and rivers. The type of habitat a caddisfly prefers is often easily identifiable by the type of case it makes.
