The adult butterfly is so common and well known to every 

 gardener and farmer, that a description of it is unnecessary, 

 suffice to say it is a small white butterfly, with a feAv black 

 spots near the margin of the wings, which measure about 

 two inches in expanse. The female butterfly deposits her 

 small yellowish eggs upon the leaves of the cabbage plant. 

 In a few days the little green larvae hatch and immediately 

 begin to feed upon the foliage. They eat with considerable 

 rapidity, and become full grown in about two weeks. As a 

 rule the larv» then leave the cabbage plants and seek some 

 sheltered place, and change to pupa', which are naked and 

 without a cocoon. Occasionally the pupju will be found on 

 the cabbage plants. They remain in the pupa state about 

 ten days, and then the adult butterfly comes forth raady to 

 deposit eggs, which soon hatch into another brood of worms. 

 There are several generations each year, and it can be read- 

 ily seen that if left to themselves, they will increase in num- 

 ber with great rapidity. This insect passes the winter in the 

 pupa state. 



Fortunately these insects have a number of natural ene- 

 mies that tend to keep them in check. The adult butterflies 

 fall a prey to birds, and a bug that catches them and sucks 

 their juices. The larviB and pupa3 fall a prey to birds, and 

 are greatly subject to the attack of certain insects both pre- 

 daceous and parasitic. The larvas are also sometimes killed 

 in great numbers by a certain disease. 



Kemedies. — The cabbage worms are readily killed by a 

 number of easily applied remedies. When the plants are 

 very young Paris green or London purple can be applied 

 without danger. It may be used either as a powder or mixed 

 with water. When. the plants are of any considerable fize 

 Pyrethrum either mixed with five times its bulk of flour and, 

 dusted on the plants, or mixed with water and sprayed upon 

 them, will prove an excellent remedy, provided the Pyre- 

 thium is good. Kerosene emulsion will kill them, but when 

 the plants are nearly headed, it may taint the leaves.
