OTHER COMMON INSECTS 



19. Codling Moth. — 



The most destructive 

 of the lepidopterous 

 insects is the codling 

 moth, already men- 

 tioned as an example of 

 metamorphosis. The 

 larvre become adult in 

 April at about the time 

 the early apple trees 

 blossom. The eggs are 

 laid on the young apples 

 and the larvse begin to 

 eat the growing apple, 

 which, as a result, in 

 many cases drops to the 

 ground. In any event 

 the quality of the apple 

 is injured. 

 In most parts of our country, there are two distinct 



broods of the codling moth, the life history of which has 



only recently been clearly understood. The eggs of the 



second brood are laid 



generally in August 



when the fruit is pretty 



well grown. The 



same damage is done as 



to the early apples, but 



as each mature female 



lays a hundred or more 



eggs and as the most 



important apple crop is 



the late one, the chief 



damage is at this time. Figure 30. — A Geometrid Moth.
