New Zealand Glowworm
A bioluminescent fungus gnat larva endemic to New Zealand. Produces blue-green light to lure prey into sticky silk threads dangling from cave ceilings.
Did You Know?
These glowworms use a completely different bioluminescent chemistry from fireflies — their luciferin is unique in the animal kingdom, derived from xanthurenic acid.
Cold-water Glacier Midge
A cold-adapted midge found in high-altitude streams fed by snowmelt. Its larvae are among the first colonizers of newly formed glacial streams.
Did You Know?
Adults can emerge and fly at temperatures just above freezing.
