screwworm
Parasitic fly larva
Screwworm is the larva of a fly that infests open wounds on livestock and other warm-blooded animals, including humans.
The larvae burrow into living flesh, feeding on tissue and causing severe damage or death if untreated.
The name refers to the larva's screw-like appearance and burrowing motion.
Once a major agricultural pest in the Americas, screwworm has been eradicated from North and Central America through sterile-male release programs.
