Predators of larvae and pupae include fish and other aquatic animals, such as other insects and crayfish. Predators of adults include birds, bats, frogs, salamanders, insects, and spiders. Usually, large numbers of Northern Caddis Flies hatch at the same time.

A few species of caddisfly larvae do not construct cases. Most of these species are predators. Free-living caddisflies are not as commonly found as case-making caddisflies. Some free-living caddisfly larvae grow to nearly 1 1/2" long.

Some caddisflies protect themselves from predators by building portable cases out of local materials - such as pebbles, sand, and aquatic plants - that are cemented together with silk or mucus.

Some species do not live in cases, using their hooks instead to cling to the stream bed and also to drag themselves backwards to escape from predators. ... The Caddisfly Larva eats algae and plants (living and dead). Some species feed on other insects and spin silky nets to capture their prey. Some eat the larvae of...

Field work has shown that caddisfly larvae prey upon newt eggs, despite the presence of TTX. Because adults do not defend eggs, ... The relationship between newt eggs and their caddisfly predators, the effect of TTX on this relationship, and the potential for co-evolutionary interactions in this system will be discussed.

All caddisfly larvae live in aquatic environments; they may be herbivores, scavengers, or predators.   In most cases, the predatory species are free-living or spin silken structures in the water (webs or tunnels) to entrap prey.
