The boxelder bug, Boisea trivittatis, formerly Leptocorouos trivittatis, is a true bug, of the order Hemiptera, which means half-winged. Most Hemiptera are "good bugs" that is, predators such as Aquatic Bugs, Damsel Bugs, Ambush Bugs, Assassin Bugs, etc. The boxelder bugs are sort of in the middle. They do very little damage to the trees they attack, but at certain times of the year they can become a nuisance. Boxelder bugs develop by gradual metamorphosis, from egg, to nymph, then to adult.
