ENEMIES AND DIFFICULTIES. 75 



its head is darker, and its body more hairy. Figure 31 

 shows the larva and perfect insect of the Vine worm, and 

 the appearance of tlie vines after its attacks. 



James A. Fenwick, speaking of the vine worm, says: 

 " It feeds on the under side of the leaf, leaving nothing 

 hut the veins, and increases rapidly to a countless multi- 

 tude, causing the meadow infested by them to appear as 

 if scorched by fire ; hence their name, ' fire worm.' Upon 

 observing a meadow infested by them in April, I found 

 the worms feeding upon the leaves, and partially sur- 

 rounde<l with webs. In June I noticed they had webs 

 enclosing clusters of vines (ignorant persons thinking 

 them spider webs), apparently for shelter from the 

 weather. Upon approaching them with a heavy tread, the 

 worms suddenly disappeared, dropping to the ground ; 

 but, stepping noiselessly, and touching the webs, the 

 worms would drop into my hand, making, at the same 

 time, vigorous efforts to escape. By the close of July 

 not a worm could be seen, but the webs remained; 

 doubtless the worms had enclosed themselves in cocoons. 

 In August, the millers arose in numbers around my feet, 

 taking short flights, and again settling upon the ground ; 

 by September these had disappeared, and the worms had 

 increased a hundred-fold; evidently showing that two 

 generations of these insects were hatched in one season." 



In Packaid's Guide to the Study of Insects may be 

 found the following minute description of the vine worrn^ 

 and the moth, of which it is the larva: "Mr. Fish has 

 discovered an undescribed species of Anchylopera^ which 

 feeds in the cranberry, and which we may call the Cran- 

 berry Anchylopera [A. vaccinlana). The moth is dark 

 ash, the fore-wings being whitish, dusted with brown and 

 reddish scales, wdth wdiite, narrow bands on the costa, al- 

 ternating wath broader yellowish -brown bands, five of 

 w^hich are several times larger than the others, and from 

 four of them regular indistinct lines cross the wing. The
