Larva. 



1. Description. The larva is a stout, cream-colored maggot, with- 

 out legs and without a head. It is about 5-16 of an inch in length and 

 tapers gradually to the anterior end. Although there is no true head, 

 there are two large hooks on either side of the mouth, with which 

 the maggot rasps the cells of the apple pulp. The liberated juices are 

 then absorbed, and the dead cells turn dark, forming the brown tracks.
