The average length for an adult stink bug is 3/4 inch. Their body is shaped similar to a shield and the most common colors are green or brown. Their antennae are fairly long.
The stink bug is a good flier, who can become a pest in the fall when they try to enter structures for warmth. They received their name, because of the foul odor they secrete, which is used as a defense mechanism.
Both the adult and nymphs feed on sap, seed pods and nectar. Their feeding can damage plants and cause deformed buds and fruit.
Stink bugs generally mate in spring. The adult female will lay her eggs on leaves which she will aggressively guard. The eggs hatch in about 30 days.
