Net-spinning larvae are apparently territorial and defend space around their retreats from other competitors. Dont worry though; these insects are too light for humans to feel them crawling on their skin. The larvae are sensitive to pollution and thus serve as an indicator of water quality. Caddis flies are important to freshwater ecosystems because they clean the water by consuming plant and animal debris and serve, as . Climbers or crawlers resembling hermit crabs. Rhyacophilidae (Free-living caddisfly larvae) Caddisfly cases are often found attached to rocks near waterfalls, streams or lakes where they feed on algae from the surface of stones.
