The Moths and Butterflies 



435 



The beautiful little Ampelophaga myron, with soft red-brown hind wings 

 and brownish-gray fore wings, patterned as shown in Fig. 624, has a pea- 

 green, cream-banded, and yellow and lilac spotted larva known as the hog- 

 caterpillar of the vine, so named from its form the third and fourth seg- 

 ments being greatly swollen, the head and first two segments small and 

 its destructiveness to grape-vines. When ready to pupate it spins a brown 

 silken open-meshed cocoon on the ground under leaves or other rubbish.

 in middle; and P. myops, below. (After Lugger; natural size.) 



A. versicolor (PL I, Fig. 3) is a beautiful cousin of myron with greenish 

 overlaid on the brown. An extremely slim, slender-bodied, and slender- 

 winged sphinx is Charocampa (Theretra) tersa (PL VIII, Fig. 2), found in the 

 northern states. It is very swift. An abundant and familiar hawk-moth found 

 all over the United States is the white-lined sphinx, Deilephila lineata (PL VIII, 

 Fig. i). Its caterpillar feeds on various plants, as grape, apple, watermelon, 

 buckwheat, turnip, and purslane; the latter seems to be the preferred plant.
