. The animans and man; an elementary textbook of zoology and human physiology. FIG. 233. The monarch butterfly, Anosia plexippus (above), distastefulto birds, and the viceroy, Basilarchia archippus (below), which mimicsit. (Natural size.) colored that the birds generally recognize it before actuallynipping it, and thus it often escapes with its life—for tobe nipped is death to a butterfly. Other conspicuouslymarked butterflies and insects and some other forms, inparticular a famous little blue and red frog of Nicaragua, are thought to be so marked for a similar reason. They areeasily recognized as animals having a bad taste and so are 448 THE ANIMALS AND MAN generally let alone. Accordingly naturalists believe thatconspicuous color and markings often advertise some disa-greeable quality or some special means of defense in theanimal bearing them and thus ward off its enemies.. FIG. 234. Various moths and wasps, the moths having the appearanceof wasps, probably through mimicry, for the sake of the protectionafforded by their being mistaken for the stinging insects. (Naturalsize; photograph by the author.) Mimicry.—Certain other insects derive strange advan-tage from the inedibleness of the warningly colored bad-tasting kinds. There is, for example, another kind ofbutterfly called the viceroy (fig. 233), which looks so muchlike the monarch (although not nearly related to it), that COLORS AND MARKINGS OF ANIMALS 449 it requires careful examination to distinguish the two kinds.But the viceroy is not inedible. And yet it, too, escapesvery largely the attacks of birds because they mistake itfor the other. By mimicking in color and pattern the ap-pearance of the inedible monarch it gains a great advantage.Numerous other examples of protective mimicry are knownamong butterflies, especially tropical ones. Other uses of color and markings not yet under-stood.—Pro
