Streamlined Backswimmer
A pale backswimmer with mottled wings found in still and slow-moving waters across North America. Like other backswimmers, it hangs just below the water surface film waiting for prey vibrations. It is a strong underwater swimmer.
Did You Know?
It senses prey by detecting surface water vibrations with specialized sensory hairs on its legs, effectively turning the water surface into a detection web.
Slender Pigeon Louse
A long slender louse found between the barbs of wing and tail feathers of pigeons and doves. It is one of the most studied louse-host systems in biology.
Did You Know?
This louse has become a model organism for studying coevolution, as its evolutionary tree closely mirrors that of its pigeon host species.
