Key Visual Features
The green stink bug (Chinavia hilaris) is a common shield-shaped true bug found in gardens and farmland.
- Size: Adults measure roughly 14-19mm long.
- Color: Bright uniform green across the back, often with a narrow orange or yellow line bordering the edge of the body.
- Body shape: Classic shield or pentagon shape when viewed from above, wide across the shoulders and tapering toward the rear.
- Wings: Two pairs, with the forewings partly leathery and partly membranous, folded flat over the back at rest.
- Antennae: Five-segmented, often with subtle darker banding near the tips.
- Legs: Six slender legs, typically green to match the body.
Where and When You'll See It
Green stink bugs are found on a wide range of host plants, including tomatoes, beans, soybeans, and various fruit trees, in gardens, agricultural fields, and orchards. They are most visible from late spring through fall while feeding and mating on plants. As temperatures drop, adults seek shelter under bark, leaf litter, or other protected spots to overwinter, re-emerging the following spring.
Similar-Looking Bugs
- Brown marmorated stink bug: Mottled brown rather than green, with distinct white banding on the antennae and legs.
- Southern green stink bug: Very similar bright green color, but nymphs and some adults show small dark spots that green stink bug nymphs typically lack.
- Other shield bugs and leaf-footed bugs: Vary in shape, with leaf-footed bugs showing flattened, leaf-like expansions on the hind legs that green stink bugs lack.

- Bright green, shield-shaped body about 14-19mm long

Frequently asked questions
How can I tell a green stink bug from a brown marmorated stink bug?
Color is the fastest clue: the green stink bug is a solid bright green, while the brown marmorated stink bug is mottled brown with distinctive white bands on its antennae and legs.
What plants are green stink bugs usually found on?
They are commonly seen on tomatoes, beans, soybeans, and various fruit trees, where they feed and rest on stems, leaves, and developing fruit.
Do green stink bug nymphs look like the adults?
No, nymphs are rounder and often show a patterned combination of black, green, and orange before gradually developing the solid green adult coloring after several molts.
When are green stink bugs most active?
They are most visible from late spring through fall, then seek sheltered spots like bark crevices or leaf litter to pass the winter as adults.
