beskrivelse:

Original description on website: "Caddisfly adults resemble moths, but the wings are covered with fine hair instead of scales. (Trichoptera = "hair wing.") Caddisfly larvae are a favorite food of many fish, including trout, and are used as bait by sport fishermen. The larvae are especially sensitive to water pollution and their numbers can be monitored over a period of time as a good indicator of water quality.

These primitive flying insects are most abundant near well-aerated streams and fast-flowing water, but also frequent lakes, ponds and marshes. This specimen was found at the west branch of the DuPage River, a fairly sluggish body of water, home to both large and smallmouth bass, walleye, and panfish such as bluegills and sunfish."
