Stink bugs

Stink bugs are a large family of insects that spray a potent stench when frightened to ward of predators. They can be a pest in some regions, as they eat citrus leaves, damaging the tree. 
Stink bugs could be a valuable food resource, as at least some species can be eaten, after special preparationhttp://www.scienceinafrica.co.za/2003/october/stinkbug.htm.
