Caddis fly larvae work an important gig hoovering up aquatic vegetation, keeping a river from getting overgrown. As flying adults, they serve as a critical food source for bats, frogs, and spiders.

You’d be right to think the latter. The bundles are actually caddisfly cocoons, assembled meticulously by larvae that live in them for protection while they wait to emerge out of the water as winged ...

Caddisfly larvae usually use natural material such as sand, gravel and plant debris to build their protective casings, weaving pieces together using self-produced silk.

Larvae of the stream caddisflies, Brachycentrus americanus and Brachycentrus occidentalis, were studied in eight simulated stream channels to determine their behavioral responses to temperature, food ...

Caddisfly larvae build armor out of pebbles.You may know the caddisfly as one of the flies that fly fishers emulate when creating lures. (Trout love them.) But when this fly is in its larval stage ...

Adult caddisflies mostly eat algae, although some feed on other insects. Their larvae provide an important food source for fish and for other aquatic insects. Adults only live for about a month.

Hubert Duprat moved some of the caddisfly larvae into a home aquarium, providing them only with gold, jewels, and semi-precious stones to build their sheaths. The material used include gold ...

Two hypotheses exist as to the function of the tubular cases constructed from silk and debris by caddisfly (Trichoptera) larvae. One proposes that they provide protection for the larvae by ...

They may seem like innocent artisans, crafting intricate homes reminiscent of cathedrals, but caddisfly larvae are actually aggressive cannibals, often mobbing other larvae and eating them when living ...
