into the surface of the fruit at the calyx end. When the fruit is 

 ripening, the damage is more conspicuous and more serious. At 



this time the second 

 brood larvae are ac- 

 tive, and blotch mines 

 are made just under 

 the skin of the apple. 

 The larva within may 

 penetrate the pulp to 

 a depth of half an 

 inch, or occasionally 

 nearly to the core. 

 Frequently the work 

 goes on for some time 

 after the fruit is 

 picked. 



The parent insect 

 is a small moth. Eggs 

 are laid soon after the

 long. Pupation takes place under scales of bark on limbs, or some- 

 times in the calyx end of the fruit.

 cocoons, in situations similar to 

 those of the first brood, or in barrels 

 in which fruit has been placed.
