one brood in the North. These insects can be 

 successfully combated with a poison spray ap- 

 plied early before the buds open. 



4. The Cigar Case Bearer winters in Its 

 case attached to a twig. When the buds begin 

 to open in the spring it moves to them, carrying 

 its case with it, and begins to feed on the young 

 and tender buds. By the time the leaves are 

 well open, it has fed a good deal on the tender 

 buds and young leaves and is ready to make a 

 new and larger case. This it does by cutting 

 a leaf to suit and then rolling It up In the form 

 of a cigar, whence its name. In this case the 

 larvae continue feeding about a month, caus- 

 ing much Injury to the leaves, although this Is 

 not as serious as the mutilation of the young 

 buds In the spring, before the tree Is fully 

 leafed out. 



About the last of June pupation takes place 

 and In about ten days the moth emerges. The 

 eggs are then layed along the midribs of the 

 leaves and hatch in about fifteen days. The 

 newly hatched larvae become leaf miners dur- 

 ing August, and migrate to the branches again 

 in the fall where they pass the winter. These 

 leaf and bud eating insects can be destroyed by 

 applying a poison to the buds before they open
