Saddle-Case Caddisfly
A small caddisfly whose larvae build distinctive saddle-shaped cases from tiny stones. When it pupates, it cuts the case free from the rock and seals itself inside.
Did You Know?
Saddle-case caddisfly larvae graze algae so efficiently that they can create visible clean patches on otherwise algae-covered stream rocks.
Iron Blue Dun
A small dark mayfly that hatches prolifically on cool overcast days. Nymphs are found clinging to stones in moderate to fast current.
Did You Know?
Hatches are most prolific during rain and cold snaps, making it a favorite species for wet-weather anglers.
