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.
Mountain Seed Bug
A small seed bug found in alpine and subalpine grasslands across Europe. It feeds on seeds and sap of various mountain plants.
Did You Know?
Large swarms sometimes form on mountain summits during warm summer days.
