very effective in checking the ascent of caterpillars when applied 

 on bands of heavy paper to the trunks of trees. Where the 

 number of caterpillars jarred from the trees is excessive it is 

 expedient to kill them. A hand spray charged with kerosene 

 or gasoline is a useful means to this end. 



Fowls and Pigs. — Hens will devour these caterpillars greedily 

 and if given the range of an orchard will eat great numbers of 

 the caterpillars which drop to the ground or descend to pupate. 



Pigs pastured in an orchard will, by rooting up and eating 

 the pupse, prevent great numbers of saddled prominents and 

 other moths from emerging and depositing eggs for the follow- 

 ing season. 



Apple-Leaf Bucculatrix. 



{Bucculatrix pomifoliella.) 



The larva of this insect is about one-fourth inch long when 

 mature, cylindrical, tapering at both ends. Joints of the body 

 rounded and prominent, color dark yellowish, with a greenish 

 tinge and reddish shades on the anterior segments. The larvae 

 are active and when disturbed suspend themselves by a silken 

 thread. 



The cocoon is dirty white, slender, about one-fourth inch 

 long, ribbed longitudinally by about six prominent ridges, 

 oblong, tapering at both ends, flattened on the side to which it 

 is attached. Usually fastened to the twigs and branches in 

 groups, (fig. 14).
