Southern Net-Winged Midge
A net-winged midge endemic to southern Appalachian mountain streams. Larvae graze diatoms from smooth rock faces in fast cascades.
Did You Know?
Each suction disc on the larva generates enough force to support the entire body against rushing water.
Fever Fly
A small, shiny black march fly with spiny front tibiae used for digging. It was once believed to cause fevers in humans, hence its common name, though it is completely harmless.
Did You Know?
Its spiny front legs are used by females to dig into soil for egg-laying, an unusual adaptation among flies.
