Picromerus Predatory Bug
A dark brown predatory stink bug with two prominent pronotal spines found across Europe. It is an important natural enemy of caterpillars in forests and orchards. Adults have a distinctly spiny appearance.
Did You Know?
It hunts by gripping caterpillars many times its own weight with its strong forelegs while injecting paralyzing saliva, then draining the prey over several hours.
Western Boxelder Bug
A red and black bug very similar to the eastern boxelder bug but found in western North America. It forms large overwintering aggregations on buildings and fences near boxelder trees. It is a nuisance pest but causes no structural damage.
Did You Know?
When crushed, it stains fabrics and surfaces with a reddish-orange dye from its body fluids, which is why it should be vacuumed rather than squashed when found indoors.
