The insect world never ceases to amaze. These colorful bugs boast familiar patterns like faces or tribal masks on their shields. While potential predators waste prescious time wondering whether it's food, enemy or prey, the masked creatures plot their protection tactics or escape.
These mini warriors have pretty smart warfare defences. Shield bugs, or stink bugs, have glands in their thorax (the part between the head and the abdomen) between their first and second pair of legs that produce a foul-smelling liquid, which is used for defense and released when the bug feels threatened.
This is a picture example of how the sheild pattern resembles a face. Like a huge sign saying "don't even think about it" to predators - including humans - the casperonian looks slightly grumpy, and for good reason. Just recently, scientists have discovered the nutritional value of edible stink bugs. They're a good source of protein, fat, amino acids, vitamins and minerals.
