Description. 



The Codlin moth (Carpocapsa pomonella, Linn). It is so called 

 because in Europe it mostly attacks the early culinary or "coddling" 

 varieties.

The moth itself is 

 about half an inch in 

 length,when at rest, and 

 measures about three- 

 quarters of an inch 

 across the expanded 

 wings. The fore wings 

 are grey, crossed with 

 wavy brown lines, and 

 are ornamented with 

 patches of metallic 

 bronze scales near the 

 margin. The hind 

 wings are light brown. 

 The male is supplied 

 with a dark narrow 

 space on the lower 

 surface of the front 

 wings, and a narrower 

 stripe on the upper 

 surface of the hind 

 wings. These dark 



spaces, says Lea, are due to hairs, and are absent in the females. 



The egg is white, scale-like, and flat. Smaller than the head of 

 a pin, it is not easily seen on the fruit until the young grub has 

 left it, when it soon after falls or is blown off. 



The larva, or grub, on hatching, is one-sixteenth of an inch in 

 length, and, when full grown, ten times as large, or five-eighths of 

 an inch. It is of a fleshy pink colour, and is covered with a few 

 stiff hairs. The male, says Lea, can be distinguished from the 

 female by the presence of a small dark space in the centre of the 

 body, that can be seen through the skin. The grub of the light 

 brown, or false codlin moth (Cacsecia), is chiefly differentiated by its 

 dirty green colour, besides being considerably thinner. 



The pupa, or chrysalis, is brown, and about half an inch in 

 length ; when empty, it is a very pale brown. 



The cocoon is made of white silk, and is joined to, and more or 

 less concealed by, the bark or bandage, wherever it is placed ; it is 

 never loosely placed, and frequently the grub eats a small hollow 

 space for its reception. I have often seen these cocoons between 

 the nailed end of the battens, and the end or centre board of fruit 

 cases, in places where one could hardly insert the blade of a knife, 

 the grub having practically eaten for itself a hollow chamber, where 

 it spins its cocoon.
