Shield Bug
Also called stink bugs for the foul-smelling liquid they release when disturbed. Changes color from bright green in summer to bronze-brown before overwintering.
Did You Know?
Shield bugs can change color with the seasons — they produce green pigment in summer for leaf camouflage and switch to brown in autumn as leaves change.
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.
