a back shot of the stink bug ... it didn't release gas. thank u :)
Stink bugs are in the Pentatomidae, which are bugs that produce odors as their self-defense. There are over 200 different species of stink bugs throughout the world with the majority of them eating strictly plants; however, some are predators and eat other bugs.
The "stink" that both shield bugs and stink bugs release when disturbed or crushed is a liquid that is produced and stored in glands that are found in the bug's thorax. The foul smell is meant to serve as a defensive agent, keeping away predators who may want to feast on the shield or stink bug.
