The eastern Boxelder Bug (Boisea trivittata) pierces and feeds on maple seeds. They are not generally considered pests unless they invade homes or destroy fruit in the process. If they do invade homes, their excrement can stain the upholstery. They are also known as the boxelder bug.

The western box elder bug (Boisea rubrolineata) is most recognized by the annoyance it causes during the fall, as it has a tendency to invade homes in search of warmer protection. It has a prominent red border against a dark body that makes it easily identifiable. Other than this, they are a fairly harmless insect which may only damage some commercial fruits occasionally.

The female red-Shouldered Bug( Jadera haematoloma), is known for the red eyes and red "shoulders". This bug lives throughout the United States and is usually considered a nuisance pest indoors. They do not bite people but can leave fecal matter which may stain walls, upholstery, and furniture.

Rhopalus subrufus is a species of scentless plant bugs belonging to the family Rhopalidae, subfamily Rhopalinae. Length is about 7 millimetres (0.28 in). It can be distinguished for its membranous forewings and the connexivum with dark and light stripes. It mainly feeds on Hypericum species, but also on many other plants. It is found in most of Europe.

The marsh rhopalid is a striking organism with a shield-shaped exoskeleton, marked by a distinctive pattern of spots and lines that serve as a form of camouflage among the foliage where it resides. Primarily herbivorous, this species has a rostrum that pierces plant tissues to access sap, a feeding behavior that begins at a very young stage and continues throughout its life cycle. The adaptability in its diet reflects an evolutionary specialization to survive in various ecological niches.

Stictopleurus punctatonervosus can reach a length of 0.26–0.35 in. These bugs have a regularly punctuated pronotum, a banded connexivum and a rounded tip of the scutellum. The body is gray-brown to black, while the abdomen is often greenish. In the anterior margin of the pronotum there are quite difficult to discern dark marks similar to two half circles or to reading glasses.

With a life cycle including eggs that overwinter, knapweed rhopalid transforms from flightless nymphs to winged adults, capable of flight. Feasting mainly on plant juices, these insects harbor symbiotic bacteria within specialized cells known as bacteriocytes, which aid in nutrient absorption from their diet. They exhibit various shades and patterns across their exoskeleton, which acts as effective camouflage amidst vegetation.
