and forwards she travels, bending and shaping the in- 

 curving leaf until it is rolled up into a perfectly neat 

 cylinder, the edges of which are secured by a sticky 

 cement exuded by little glands which are present along 

 the edge of the leaf. All this labour has been under- 

 taken by the little Weevil not for her own benefit, 

 but to form a safe nursery for her offspring. Within 

 the folds of each rolled-up leaf she has deposited from 

 one to four eggs, from which in due course will emerge 

 the little larvae, who, thus safely hidden from view, will 

 feed upon the soft tissues of their leafy cradle.
