Many other examples could be given. ^ Warning Coloration and Protective Mimicry. — Some insects are ex- tremely unpleasant, both to smell or to taste, while others are provided with means of defense such as poison hairs or stings. Such animals are almost always brightly colored or marked as if to warn animals to keep off or take the consequences. Ex- amples of insects which show warn- ing by color may be seen in manj' examples of beetles, especially the spotted ladybirds, potato beetles, and the like. Wasps show yellow bands, while many forms of caterpillars are conspicuously marked or colored. Some insects, especially caterpillars, are brightly colored and protrude horns, or pretend to sting when threatened with attack. These animals evidently mimic animals which really are protected by a sting or by poison, although this mimicry is not voluntary on the part of the insect. One of the best-known cases of insect mim- icry is seen in the case of the imitation of the monarch butterfly by the viceroy. The monarch but- terfly {Anosia 'phxip'pus) is an example of a race which has received protection from enemies in the struggle for life, because of its nauseous taste and, perhaps, because its caterpillar feeds on plants of no commercial Monarch and viceroy butterflies : the latter (at the right) is a Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hunter, George William, 1873-1948.
