Brown stink bug

Adults: Adult brown stink bugs are long, shield-shaped insects, grayish-yellow with dark punctures on their back, and piercing-sucking mouthparts.
The fourth and fifth antennal segments are darker in color. The ventral surface usually has a pinkish tinge. Cheeks are large, passing the clypeus in length and more pointed. The humeral angles of the pronotum are rounded. The body length varies from 10 to 15 mm for adults.
Eggs: The eggs are yellowish-translucent, but their color starts turning toward a light pink before hatching.
Nymphs: The nymphs develop through five instars that require ~29 days for development. They resemble adults but are smaller and oval. They are usually pale green.
Life Cycle and Biology. Adults overwinter in protected areas such as ditch banks, fence rows, under boards and dead weeds, ground cover, stones, and under the bark of trees. They become active during the first warm days of spring when temperatures rise above 21 C. Normally the first generation develops on wild (noncrop) hosts, while the second generation typically develops on cultivated crops.
Each female oviposits about 18 egg masses, averaging 60 eggs, over a period of >100 days. Approximately four to five weeks are required from hatching to adult emergence. Euschistus servushave as many as four to five or more generations per year in Florida. Adults are strong fliers and will readily move between weeds and other alternate hosts.
