(4) the butterfly or adult form. The appearance of the 
same individual insect and its habits of feeding and living 
are very different in the various stages of its life. 
In the northern states the cabbage butterfly lives 
over winter in the pupal stage. The pupe that are 
formed late in autumn remain in this stage until late in 
the following spring. During the summer, however, the 
butterflies emerge from pupz in from 7 to 10 days; con- 
sequently there are in tHe North at least two generations 
in a season. 
In the southern states, where the winters are very mild, 
there may be as many as six generations in a year; the 
butterflies and the caterpillars of this insect are there- 
fore present throughout the year. 
The cabbage butterfly may be fought both in the 
adult and in the larval stage. The following methods are 
recommended : 
(1) Catching the butterflies. The butterflies are active 
in their movements, but they may be captured in butter- 
fly nets as they flit about the garden. Special efforts 
to catch the females at the time when eggs are being 
laid will often greatly reduce the later work of killing 
the caterpillars. 
(2) Hand-picking the caterpillars. The caterpillars 
are sluggish in their movements and can readily be 
picked off the leaves and destroyed. At first they are 
minute, and their color is almost the same as that of the 
leaves upon which they feed, but as they grow larger they 
are more easily seen. 
A simple means of killing the caterpillars is to drop 
them into a dish containing water and a little kerosene.
