Green Sedge
A free-living caddisfly larva that does not build a case, instead roaming the streambed as an active predator. Adults have greenish wings.
Did You Know?
Unlike most caddisflies, green sedge larvae are caseless predators that hunt like underwater wolves among the stream cobbles.
Little Sister Sedge
A small net-spinning caddisfly widespread in warm-water streams. Larvae tolerate moderate enrichment better than most Hydropsychidae.
Did You Know?
Larvae vibrate their bodies to increase water flow through their catch-nets.
