CABBAGE BUTTERFLIES. 



In the list of injurious insects, Cabbage Butterflies 

 occupy a prominent place, because their field of operation 

 is so extensive, and the means of exterminating them, as 

 yet, so imperfect. 



THE EUROPEAN CABBAGE BUTTER-FLY 



(Pier is rapce.) 



was first noticed in this country in the year 1857 by a Mr. 

 Bowles of Quebec. Not long after, it spread into New 

 England and New York, and a few years later it was plen- 

 tiful all over the country. 



It passes the winter in the pupa state, the perfect insect 

 emerging early in the spring. There are about five broods
