THE APPLE LEAF HOPPER 



FALL WEB WORM, 



Hypliaiiti'ia ciiiica Dru. 



Fig. lit. Work of Fall Wt'l) Worm. OriglnaL 



Two years ago attention was drawn to numbers of unsightly webs 

 on leaflless trees, observed in different parts of the state, which 

 marked the work of the Fall Web Worm (Hyphaiitria cunea Dru.), 

 during the preceding summer. These were mostly seen in patches of 

 woodland bordering pastures and elsewhere, and occasionally upon 

 fruit and shade trees. On account of their numbers, and from the fact 

 that their work was not, for the most part, in conspicuous situations, 

 thereby securing for themselves immunity from molestation, mental 

 prediction was made that their numbers would be very largely increased 

 later. This turned out to be the case, and since land owners upon 

 whose property they occurred this year have taken very little, and for 

 the most part, no steps to eradicate them, their occurrence in large 

 numbers is to be regarded of vital importance to fruit growers, park 

 commissioners and others who are interested in preserving trees and 

 shrubbery in parks and in private grounds. 



This is the more to be deplored since perhaps none of our pests 

 lends itself more readily to preventive measures, if the sufferer will 

 but put in practice a simple method at the very first appearance of 

 its work. Arsenical sprays, it is true, are not as efficacious in the case 

 of this insect as with some other leaf-eaters, since the web worm 

 covers the small branch, or cluster of leaves upon which it is feeding,
