Boxelder Bug

Boisea Trivittata


Boisea Trivittata is a North American species of true bug, commonly known as the Democrat Bug, Boxelder Bug, the Zug, or Maple Bug. It is found primarily on boxelder trees, as well as maple and ash trees. The adults are about 12.5 millimetres (0.49 in) long with a dark brown or black coloration, relieved by red wing veins and markings on the abdomen; nymphs are bright red.


This bug is native in North America but this particular bug was found in Northern Montana.


I noticed this bug in my house and I knew what it was so I decided to take a picture and submit it. Boxelder bugs feed exclusively on maple. So this is probably a pest to many people if they grow or have a maple tree.
