is going forward, and with large creatures like these 

 caterpillars a very small quantity of light will be 

 enough to see them by, as they gently move the leafage 

 in feeding. When full-fed the caterpillar goes down 

 into the ground to change ; therefore turning up the 

 chrysalids is an easy measure of prevention with this 

 Potato-feeder. 



This family of Sphinx, or Hawk Moth, are chiefly of 

 large size, and of the shape of the Eyed Hawk Moth

(Fig. 101). The caterpillar of this feeds on Apple and 

 "Willow, and is rough, of a pale green with white 

 stripes on the side, and has a blue tail. The cater- 

 pillars of the Sphinxes are mostly much like this, and 

 the caterpillar of the Death's Head, in shape ; and this 

 family deserves a word on account of its great 

 beauty. 



The habits of the various kinds of Moth caterpillars 

 do not differ so much among themselves as those of 

 Beetle grubs. Some caterpillars of several families 

 of Cloths bore up stems or timber ; some of several, 

 or at least of two, families work together in great 

 parties, which form webs for their head-quarters ; some 

 of many of the families bury themselves to turn to 

 chrysalids. We will therefore look at the class of habits 

 together, and first take the boilers. 



There is one family amongst these, known as the 

 Clearwings, which differ from other Moths in the body 

 being usually straight and narrow, and the wings so
