Figure 17.16. A, A walking stick (Orthoptera) that has been balanced on its head 

 while feigning death. (After Schmidt.) B, A katydid (Orthoptera) on a branch. By 

 "freezing" whenever frightened or disturbed, this katydid easily passes as a leaf, com- 

 plete with veins and blotched as if with blight. Thus, immobilization is combined with 

 camouflage. (Alfred Eisenstaedt-Courtesy LIFE Magazine. Copr. 1955 Time, Inc.)
