would be infinitely more fo were it not for the number of fmall birds 

 which prey upon them, and thus lend their friendly aid to deftroy 

 thofe unwelcome intruders. They feed for the inoft part on cab- 

 bages, and fome other horticultural plants, which renders them more 

 injurious to the kitchen garden than any other. The larva is of the 

 number of thofe known in England by the trivial title of the grub, and 

 in the perfect or winged ftate it is diftinguifhed by the lefs ambiguous 

 epithet of Large Cabbage Butterfly. 



The larva of this fpecies appears in fpring, and indeed throughout 

 great part of the fummer, as there are two or more broods of them 

 every year. The appearance of thefe Butterflies on the wing in a 

 morning is confidered generally as an unerring indication that the wea- 

 ther will clear up, and the day eventually piove fine. This infe& 

 though common is certainly not uninterefting.
