Longhorned Caddisfly

Caddisflies resemble moths, but wings are hairy instead of scaly. The larvae develop inside mobile cases that are constructed from plant material, sand, pieces of snail shells or silk, depending on the species. A few species have no case and are free-living. Most species cannot tolerate pollution, so their presence is indicative to good water quality.

Adult Longhorned caddisflies have very long antennae and typically the larval cases are constructed from twigs and/or leaves and stems.
