Order: Heteroptera

Family: Rhopalidae

 

Boxelder bugs get their common name because they are a major pest of the boxelder tree. Although this species is native to the western United States, it is now found in Canada and along the East Coast-wherever boxelder trees are found. 

 

Description: Boxelder bugs are about 1/2 inch long and have an elongated, oval-shaped body. They are black with reddish lines that outline their wings. These six-legged pests have a pair of antenna with four segments.

 

Biology: The female Boxelder bug lays golden-colored eggs which turn red as the embryo develops. The eggs hatch in about two weeks. Boxelder bugs feed on boxelder tree seeds and leaves.

 

Habits: In late spring, Boxelder bugs emerge from hibernation and fly back to their host Boxelder tree. Occasionally they will also feed on different fruit trees such as plum or apple. As the cooler weather approaches in autumn, they will congregate on the south side of rocks, trees, and buildings for warmth. Soon after, Boxelder bugs will locate hibernation spots for the winter. They are a nuisance pest because they leave red fecal material on their resting places, can cause skin irritation, and produce a strong odor when crushed or handled roughly.
