Southern Green Stink Bug
Nezara viridulaAlso known as Southern Green Shield Bug, Green Vegetable Bug, Cotton Stink Bug
Southern green stink bugs pierce plant tissues with needle-like mouthparts to suck juices from seeds, immature fruits, and developing buds. When disturbed or seized, adults discharge a foul-smelling blend of aldehydes and esters from thoracic scent glands to deter predators. Adults overwinter under leaf litter or tree bark, often shifting to a dull brownish-bronze hue during cold months before returning to bright apple-green in spring.

Responsible observation
- Garden Scouting: Check the undersides of bean and tomato leaves for neat geometric clusters of barrel-shaped eggs.
- Gentle Handling: Avoid pinching or crushing the insect, as its defensive secretion leaves a stubborn scent and yellowish stain on skin.
- Seasonal Coloration: Look for bronze or rust-colored individuals during late autumn and winter diapause.
