Other Leaf-Rollers 



Three Apoderi and no more figure in the 

 European fauna. The best-known is that 

 of the hazel. This is the one to whom I 

 propose to devote my attention. I find her 

 here, not on the hazel, her lawful domain, 

 but on the common alder. This change in 

 her activities deserves a brief investigation. 



My district does not suit the hazel very 

 well; the climate is unfavourable, being too 

 hot and dry. On the high slopes of Mont 

 Ventoux it grows sparsely; in the plain, 

 except in the gardens where a few find a 

 footing, they are no longer to be seen. In 

 the absence of the fostering bush, the insect, 

 without becoming impossible, is at least 

 extremely rare. 



Long though I have been beating the 

 brambles of my countryside over an umbrella 

 held upside down, here is our Apoderus for 

 the first time. For three springs in suc- 

 cession I see the red Weevil on the alder and 

 observe her work. One tree, one alone and 

 always the same, in the osier-beds of the 

 Aygues provides me with this leaf-roller, 

 whom I now for the first time see alive. 

 The other alders round about have not a 

 trace of her, though they are only a few
