200 THE GRAPE CULTUKIST. 



woody portions. They always appear as if marshaled in a 

 straight line, and move backward as they feed ; and, like 

 Well-drilled soldiers, retire in good order. 



They are not numerous in this vicinity I have had but 

 one vine attacked by them for the past two or three years ; 

 and though they could have been easily destroyed, I pre- 

 ferred to allow a few to remain each year, as I enjoyed 

 watching these industrious little creatures. 



Mr. Harris states that only one annual brood appears in 

 Massachusetts. Two broods appeared here (in Brooklyn) 

 last season. Prof. Townend Glover, Entomologist to the 

 Agricultural Bureau at Washington, stated to me in a let- 

 ter last summer (1863), that this insect was quite common 

 in that vicinity, and had been very destructive to the grape 

 in some parts of the South. 



As the caterpillar feeds entirely upon tlie upper surface 

 of the leaves, it can be readily destroyed by dusting the 

 leaves with lime when wet with dew, or the leaves may be 

 cut off with the insects upon them and thrown into the fire. 



The canker or measuring worm is said to infest the vine 

 in some sections, and the curculio is said to sting the fruit, 

 but I have not met with either of these on the grape, and 

 presume they have not infested it to any great extent. 



LEAF ROLLERS. 



The leaf rollers are a class of insects that are becoming 

 very numerous in almost all parts of the country. There 

 are several species found in our gardens, some of which are 

 very destructive to the grape, as they commence feeding 

 upon the buds so soon as they begin to swell in the spring, 

 often being found within the half-expanded bud, eating out 

 its entire center. They continue their work after the 

 leaves expand, drawing the leaves together with their silk- 

 en thread, forming for themselves a snug retreat ; and liter- 

 ally, as some creatures of a higher order do figuratively.
