Insects Injurious to the Potato and Appi.e. 583 



are edged with a very delicate and pretty fringe of 

 tine hairs. When fully expanded the wings are about 

 three-fourths of an inch across. The sexes resemble each 

 other very closely. The larva (fig. 6, e,) is about an inch 

 long when fully grown. The head is black and the body 

 is at first whitish, but as the larva grows its color be- 

 comes flesh-colored. On top of the first segment of the 

 body is a dark colored plate. The body is covered with 

 scattered hairs. The cocoons or shells which enclose the 

 chrysalids, (fig. 6, i,)- are covered with minute fragments 

 of such substances as may be at hand. The moths lay 

 the eggs in the spring, in the flower end of the fruit, 

 (fig. 6, b,) and the worm eats into the fruit and de- 

 velops within it. It reaches its full growth in a little 

 more than a month. It then leaves the fruit and seeks 

 for some crevice in which it may hide and entering this it 

 changes into a chrysalis, in which state it remains about two 

 weeks and then emerges a complete moth which lays its 

 eggs and dies. These eggs hatch the same year, but the 

 perfect stage is not reached until the following spring, usu- 

 ally about the last of May. This pest is not entirely con- 

 fined to apple trees, but also infests pear, plum, crab apple, 

 quince, and peach trees, though to a much more limited extent. 

 Many remedies for the evil done by the codling moth have 

 been suggested by one person or another. As the apples 

 infested by the larvae of this moth are usually ready to di'op 

 prematurely, a careful gathering and burning the windfalls 

 or feeding them to hogs is beneficial. Jarring the trees 

 will bring down more of these imperfect apples, and this 

 may be repeated from time to time. The most eflicacious
