THE LARGE WHITE BUTTERFLY. 



[Pier is brasstccr.) 



I, Butterfl}'. 2, Larva. 3, Pupa. 



Although the injuries that are caused by the caterpillars 

 «of this large butterfly are far more frequently noticed in 

 market gardens and private gardens than in fields, it some- 

 times happens that considerable harm is caused by them to 

 field cabbages, thousand-headed kale^ rape, and turnips, 

 especially in fields near the sea and in small enclosures sur- 

 rounded with hedgerows. In seed-growing districts, as, for 

 example, in Romney Marsh in Kent, and in parts of Essex, 

 Lincolnshire, and other counties where cabbage, turnip, rape, 

 and mustard seeds are largely grown, the larvae of the large 

 white butterfly attack and devour the seed pods and 

 diminish materially the crops of seed. Cabbages of all 

 kinds, Brussels sprouts, broccoli, cauliflowers, and kale are 

 ■also often attacked by these caterpillars, which are so large
