320 Vineyard Culture. 



vineyards is the Desmia maculalis, or Spotted-Winged Sable, 

 better known to the vine-dresser as the Leaf-Folder. This 

 beautiful little moth scatters her eggs which hatch upon the 

 leaves into a very active, slender, green worm. 



This caterpillar secretes itself, by rolling a leaf upon itself, 

 so as to make a tube of about half an inch diameter, in which 

 it feeds. This fold of the leaf is retained securely by strong 

 bands of beautiful white silk. 



These insects begin to appear in June, and continue, through- 

 out the season, to disfigure our vines. They form the pupae 

 within these rolled leaves. They can best be attacked while in 

 the larval condition, but great dexteriy is required to secure these 

 active little caterpillars, which will quickly escape at either 

 end of the pipe in which they live. They are smooth and 

 shiny, of a pale-green, and move by wriggling to the open 

 end of their shelter, when they drop to the ground and es- 

 cape, so that many of the rolled leaves will appear empty. 

 Some of the warblers are very fond of these caterpillars. 



Pteropborus perisceidactylus, or the Gartered Grape- Vine 

 Plume, is described by Dr. Fitch, in the " New York Agricul- 

 tural Transactions," and in his <( Report," p. 1 39. He says it is 

 a pale-green worm, half an inch long, which feeds upon the 

 foliage of the grape-vine, after fastening several together with 

 silken threads, so as to form a hollow ball. 



The Obis Myron, described as the Chcerocampa Pampinatrix 

 by Harris, and often called the Vine-Dresser, is quite trouble- 

 some in some vineyards. It eats the leaves, and cuts off the 

 bunches of grapes. 



The moth emerges from the ground in June, and lays her 

 eggs upon the leaves. The caterpillar is a pale-green, freck- 

 led with pale-yellow dots ; it becomes a pale, dusky olive 

 when fully grown, and is 2.25 inches in length. 



The Procris Americana, or the American Forester, is found 

 to be quite troublesome on some vines. The worm is small, 

 and feeds in groups of twenty or more, keeping closely side
