 The caterpillars are borers — that is, they are the

 wood or pith. Fig. 109 shows the grub or larva of 

 the squash clear-wing. 



The caterpillars to the larger clear- wings (Fig. 

 105) are very much like those of the Sphinx moth. 

 Those of the smaller clear-wings (Figs. 109, 110

 chrysalis shell they work their way out of the cocoon 

 (Fig. 106) and also part of the way out of the tree
