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.
Long-winged Fungus Gnat
A delicate fungus gnat with unusually long antennae and slender patterned wings. It is often found in shaded damp woodland where it hunts small insects.
Did You Know?
Some Macrocera species have bioluminescent larvae, though less spectacularly than the cave glowworms.
