Black-Tailed Deer Fly
A small dark deer fly with mostly blackened wings and green iridescent eyes. It is an aggressive daytime biter commonly encountered near wooded wetlands.
Did You Know?
It is most active during overcast humid days and tends to bite repeatedly if swatted away without being killed.
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?
