European Firebug
A strikingly patterned red and black bug that forms large aggregations at the base of linden trees. It is one of the most recognizable insects in Europe. The bold aposematic coloration warns predators of its unpleasant taste.
Did You Know?
It was one of the first insects in which scientists discovered that the gut microbiome is essential, as germ-free individuals show stunted growth and high mortality.
Water Treader
A tiny, bright green semi-aquatic bug that walks on the surface of still waters among floating vegetation. It is widespread across the Americas and is often found on lily pads and duckweed. Both winged and wingless forms exist.
Did You Know?
It hunts by detecting the tiny ripples made by struggling prey items on the water surface, running across lily pads and open water to reach them.
