moths. Besides the leaves, the caterpillars often feed 

 upon the green fruit of the tomato, as well as upon 

 the foliage of the potato and tobacco. ' 



There is another species similar to this one, and 

 often confounded with it. The life-history and 

 habits of the two are much alike. The moth of the 

 other one is called the Carolina Sphinx (PJdegcthon- 

 tius Carolina). In the Southern States, and even as 

 far north as central Ohio, there are two broods each 

 season. 



The Tomato Worm is subject to the attacks of a 

 small, four-winged, black fly that deposits eggs be- 

 neath its skin along the back. The eggs hatch into 

 little maggots that absorb the body juices of the 

 worm, developing at its expense, and, finally coming- 

 out upon its back, where they spin white, silken 

 cocoons (Fig. 86), within which they change to pupae. 

 Shortly afterward they again change to flies that 

 gnaw out of the cocoons and fly away to continue 

 the work of destruction. The caterpillar lingers 

 awhile in a half dead condition, and finally dies.
