THE YOUNG NATURALIST. 



Rearing O. Potatoria. — On page 153, 

 Vol. I, you say in your account of rearing the 

 larva? of O do nest is potatoria that it is one of 

 the easiest larvae to rear, and that they 

 should be fed on coarse grass, supplied fresh 

 every evening. My experience was that they 

 were anything but easy to rear, for three 

 years I tried to rear them on coarse grass, 

 and failed every time, without a single excep- 

 tion they would not eat the grass. I next 

 tried them on the leaves of the common reed, 

 and have bred hundreds of them since. If 

 you give them the tops of the reeds with a 

 portion of the tops so much the better, as 

 they will spin their cocoons on the stems, and 

 the leaves will not wither away as the grass 

 does. I would strongly advise my young 

 friends to use the reed in preference to the 

 grass, if they wish to rear "Drinkers" with 

 any degree of certainty.— F. Kerry, Harwich.
