One of the most beautiful of the 100,000 known species in the order Lepidoptera are the tiger moths, moths known for the striking appeal of their distinctive coloration. This type of moth is covered with highly conspicuous orange-and-black or yellow-and-black patterns of spots and stripes. Such boldly patterned color combinations are commonplace in the animal world, serving the function of forewarning potential predators of unpleasant tastes and smells. This is unquestionably the function served by the striking coloration of the garden tiger moth, which is quite visually attractive but is also poisonous to predators. Certain glands in the garden tiger moth produce strong toxins that circulate throughout the insect’s bloodstream, while other glands secrete bubbles that produce a noxious warning smell. The tiger moth, indeed, is a clear example of a concept that many predators intuitively understand, that creatures with the brightest coloration are often the least suitable to eat.
