NUT WEEVIL. 103 



specially named pear-shaped Weevils, this idea of the 

 shape of a pear would fairly describe the general shape 

 of many of this section. (See Fig. 81.) 



The grubs, as far as they are known, are much like 

 the well-known grub of the Nut Weevil. They are 

 white and fleshy, often much wrinkled across, and 

 legless. They are usually a little bent together (like

 size. Filbert pierced by Weevil. 



Cockchafer grubs), and have a horny head furnished 

 with jaws. The pupaB are like the Weevils they will 

 turn to, but with the limbs beneath them, and 

 inactive. 



The habits of the Weevils differ very much : some 

 of the timber Weevils attack the trees in a completely 

 different way, according to whether they are feeding, 

 or boring for egg-laying ; others, such as the Turnip 

 and Cabbage-gall Weevils, cause root-galls by the 

 irritation set on foot by the egg, which they place in 

 the root ; but whether the Weevil does much harm or 

 not, the grub is always hurtful, and there are many 

 attacks which have so much in common that they 

 may be classed together to be got under by one kind 

 of remedy. 



We may first notice some of the attacks that can be 

 lessened by shaking down the Weevils.
