Family Pentatomidae
Pentatomidae, Greek pente meaning five and tomos meaning section, are a family of insects belonging to order Hemiptera including some of the stink bugs and shield bugs. The stink bug derives its name from its tendency to eject a foul smelling glandular substance secreted from pores in the thorax when disturbed. The chemicals involved include aldehydes, making the smell similar to that of coriander; whether or not a human finds the smell unpleasant or pleasant may be genetic. In some species the liquid contains cyanide compounds with a rancid almond scent. This is a form of antipredator adaptation.
