Description

Typical of other stink bugs, has a shieldshaped body and emits a pungent odor when disturbed.

With a mottled brown, 1/2 in. body, it has characteristic alternating dark and light bands across the last two antennal segments that appear as a single white band in both nymphs and adults (the most distinguishing characteristic). Learn more here.

Host Plants

Pests of various crops, but in the U.S. it has been primarily reported as a household nuisance and ornamental pest. Has been found feeding in apple orchards, and in Asia, feeds on ornamental plants, weeds, soybeans, apples, peaches, figs, mulberries, citrus fruits, and persimmons.

Pathway of Introduction and Spread

Introduced from Asia, has been expanding its range since its U.S. discovery in Allentown, Pennsylvania, in 2001. Spreads by hitchhiking or through commercial sale of infested host plants.

Symptoms

Small necrotic spots on fruit and leaf surfaces often result from feeding damage.
