October Caddis
A large orange-bodied caddisfly that hatches in autumn on western North American rivers. It is one of the most important late-season food sources for steelhead and salmon.
Did You Know?
October caddis larvae build massive cases from pebbles and can be so abundant that they visibly alter the streambed substrate.
Sand-Case Caddisfly
A caddisfly whose larvae build smooth, curved cases entirely from fine sand grains cemented with silk. Adults are dark with hairy wings.
Did You Know?
The curved sand-grain cases built by these larvae are so precisely constructed they resemble tiny miniature architectural works.
