Cosmopteryx clemensella Stainton. 



The larvae of this species mine the overwintering leaves of 

 Car ex la.riflora var. latifolia, making long semitransparent 

 irregular galleries, often deserting one mine to form a new 

 one. The larvae feed during t] u . f a n anf j ca rly winter, when 

 the weather is sufficiently mild, and become full fed in the 

 spring. They pupate in a wrinkle in the leaf, and the moths 

 appear in May and June. There is apparently hut one gen- 

 eration a year.
