Philopotamidae is a family of insects in the order Trichoptera, the caddisflies. They are known commonly as the finger-net caddisflies.
The aquatic larvae of these caddisflies spin mesh nets of silk in flowing water to catch food. A larva can spin over a kilometer of extremely thin silk to create its intricate net.
