Cactus Bug
A slender coreid bug that feeds on prickly pear cacti in arid North American habitats. Feeding damage causes characteristic yellow spots on cactus pads.
Did You Know?
It was investigated as a biological control agent against invasive prickly pear in Australia.
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.
