Green Stinkbugs are
bright green with yellow, orange, or red edges. They have
black spots on their sides and grow up to 3/4 inch long.
Stinkbugs are shield-shaped (think of a shield from Medieval
times). Green Stinkbugs live in
fields, gardens, and the edges of woods. They get their name
because of the foul-smelling liquid they release when
something disturbs them. Copyright, Oklahoma State

Rice Green Stinkbugs mate in
the Spring. Females lay barrel-shaped, green eggs together
under a leaf in the pattern of a honeycomb. Eggs hatch in
about a week. Green Stinkbug
nymphs
are born from the eggs. Nymphs look a little different from
adult
stinkbugs. Nymphs are black at first, then they turn green
with red, yellow, and black markings. Their bodies are
oval-shaped. These insects do not have
a pupa (resting) stage. Instead, nymphs eat and grow,
shedding their skin several times. Each time a nymph sheds
its skin, it looks a little more like an adult. It takes a Green Stinkbug
nymph about a month to turn into an adult. If the weather stays
warm, an adult stinkbug lives about two months. If a young
stinkbug is around when the weather gets cold, it will
hibernate
in leaf
litter or a tree
hole until Spring.



Green Stinkbugs eat a wide variety of plants. In fact, they eat just about anything. Some of their favorite food sources are Black Cherry, Flowering Dogwood, Evergreen Blackberry, and pine trees. Stinkbugs will suck juices from leaves, flowers, fruits, and stems. They have sharp mouthparts which they use to pierce the plant.
Adult Green Stinkbugs are strong fliers, but nymphs cannot fly.
Predators of stinkbugs include many species of birds, toads, spiders, and other insect-eating animals.

Relationship to Humans:
Green Stinkbugs can be great pests. Besides all the weeds, shrubs, and trees they eat; they also eat crops, including apples, cherries, peaches, eggplants, tomatoes, beans, peas, and corn. When there are many stinkbugs together, they can cause a lot of damage. Otherwise, they can be helping to control plant growth.
