Okamoto : On the Life-history of the Apple Fruit-miner, Argyresthia conjugella Zell. 2 17 



last abdominal segment has a number of long spines with hooks at the end. These 

 hooks are fastend in the silk and aid the pupa in holding its place in the cocoon. 



The Adult Insect. 



After the pupa has thrust itself out of the cocoon, the pupal skin splits down 

 the back, and the moth forces its way out by spliting away the head end of the 

 pupal skin. 



The insect is at first wet, and the body wall is soft. The wings increase 

 several times in size, and as the body dries it grows more rigid. When the wings 

 were fully expanded the moths would often hold them over their backs for a few 

 minutes. The whole process of emergence takes from fifteen to thirty minutes. 



The adult insect or moth is quite variable in size. The wings when fully 

 expanded measure from 10 to 12 mm. The length of the body is from 5 to 6 mm. 

 The whole insect is covered with scales having varying color. The body is dark 

 gray. The head covered with long, yellowish white hairs. The antennae are 

 very long and black in color with many yellowish white rings. The anterior wings 

 are dark gray, and very slender. There is a very broad silver-white band along the 

 hind margin, that extends to the middle part from the base of the wing. In the 

 middle portion of the wing a large black band across the wing is to be seen, and a 

 yellowish white spot on the outer margin. On the anterior margin there are many 

 short yellow lines. Tlie posterior wing is smaller and darker than the anterior, 

 acinaciform and margined with long hairs. 



Habits of the moth — The moth are but rarely seen in orchards. They spend 

 most of their time resting in the foliage of the apple. When disturbed, they ily 

 away so quickly that the eye is unable to follow them in their erratic flight. Ac- 

 cording to my observations the moth feed on the water, and are generally not 

 attracted to lights at night.
