Elementary biology; an introduction to Elementary biology; an introduction to the science of life elementarybiolog00grue Year: 1924 Fig. 170. Walking-leaf insect This insect, related to tlie locust and the katydid, resembles the foliage upon which it crawls. ( X 3) Fig. 171. Tree hoppers (Memluvcis biuotata) These small insects resemble miniature quail quite as closely as other animals 'mimic ' their models. Yet there is no conceivable advantage to the insect in this resemblance 402. Protective resemblances. In some animals the mottlings and striping are often very close imitations of particular kinds of backgrounds, and this resemblance is further heightened in many animals by peculiar forms (see Figs. i68, 170). 1 The art of ' camouflage ' as developed during the Great War rested largely on the observations of naturalists on protective coloration.
