The caterpillars of the large moths are all enormous 

 eaters, and many of them are the great green " worms," 

 so called. The "potato worm" (Fig. 7), — found also on 

 tobacco and the tomato, — is the larva of the hawk-moth 

 shown in Fig. 6. This larva will often remain for some 

 time motionless on a stem with the head and front part of 

 the body stretched upward, and from this habit the moths 

 are named the Sphinxes.
