A Technical Report from The Bartlett Tree Research Laboratories
Boxelder bug (Boisea trivittata) is a true bug (order Hemiptera) in the family Rhopalidae. Although most members of this family live and feed on herbaceous plants, this insect is generally associated with trees. Its range includes much of the continental United States and southern portions of Canada. Boxelder bug is primarily a nuisance pest to humans and causes little damage to its host trees.
