ATTACKING THE LEAVES. 163 



wings expand from three and a half to four inches. The 

 wings are of a purplish-brown color, the anterior pair having 

 a stripe of white on their front edge, and one of a fawn color 

 on their outer edge; there are also three or four oblique black 

 streaks, and a black dot on the white stripe. The hind wings 

 have two whitish, wavy stripes, with a fawn-colored stripe 

 also on their outer edge. The head and thorax are blackish 

 brown, with a whitish-fawn color at the sides; the eyes are 

 very prominent, and the snout-like projection in front consists 

 of the two palpi or feelers, within which lies the proboscis or 

 tongue, snugly coiled up between them like the mainspring 

 of a watch ; in the figure this proboscis is shown partly ex- 

 tended. When stretched to its full length, it is as long as the 

 body, and is used by the insect in extracting honey from 

 flowers. The body is brown, with a central line and a band 

 on either side of black, the latter containing four or five dingy- 

 white spots. 



The moth deposits her eggs singly on the leaves of the 

 plum. The egg is about one-fifteenth of an inch long, slightly 

 oval, with a smooth surface, and of a pale yellowish-green 

 color. It hatches in from six to eight days, when the young 

 larva eats its way out through the side of the egg; its first 

 meal is usually made from the egg-shell, which it partly or 

 wholly devours. 



The newly-hatched larva is one-fourth of an inch long, of a 

 pale yellowish-green color, with a few slightly-elevated whitish 

 tubercles on every segment, from each of which arises a single 

 fine short hair; the caudal horn is black. The full-grown 

 caterpillar is about three and a half inches long (see Fig. 171), 

 of a beautiful apple-green color, with a lateral dark-brown or 

 blackish stripe. On each side of the body there are seven 

 broad ol^lique white bands, bordered in front with light 

 purple or mauve; the stigmata or breathing-pores, which are 

 ranged along each side of the body, are of a bright orange- 

 yellow. The caudal horn is long, dark brown, with a yel- 

 lowish tint about the base at the sides. After satisfying its
