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.
Secondary Screwworm Fly
A blow fly that breeds in carrion and occasionally infests wounds in livestock. It is widely used in forensic studies in the Americas.
Did You Know?
Unlike the primary screwworm, it only feeds on dead tissue rather than living flesh.
