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.
Ambush Bug
A small crab-like bug that waits motionless on flowers to ambush visiting pollinators.
Did You Know?
It can capture prey many times its own size with its powerful raptorial forelegs.
