The caterpillars of certain moths known as the looping 

 caterpillars, or measuring worms (Fig. 235), show a re- 

 markable resemblance to 

 the branches on "which thej- 

 live. They are coloi'ed like 

 the bark and have the re- 

 markable habit of holchng 

 fast by their false hint! legs, 

 while the long slender Ijody 

 pr(_)jects outward hke a 

 twig. 



Perhaps one of the most 

 remarkalile resemblances is 

 the Kallima, or leaf butter- 

 fly, of India. Figure 236 

 shows the reiuarkal)le simi- 

 larity of this insect to a 

 leaf. Wlien it alights on a 

 bi-anch, its wings are held 

 vertically with tlic upper 

 sides folded together so 

 that only the umk'r sides 

 show. Note the dark hne 

 running through the middle 

 of the wings like the mithil) 

 of a leaf. Note also the 

 small projection on the end 

 of the wing that resembles the petiole of a leaf. The legs 

 are usually more or less hidden, and, inoi-e than Ihat, are 

 so colored that the}' arc incons[)icuous. The upix'r sides
