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.
Apple Caddis
A caddisfly of Appalachian streams that builds tapered square cases from plant material. Larvae orient their cases facing into the current for filter feeding.
Did You Know?
The square cross-section of the case is thought to reduce drag in fast currents.
