LARGE CABBAGE BUTTERFLY, 191 
pillars, which are often to be met with so late as 
the end of October, or even in November. The 
large and continuous supply of this little parasite 
throughout the summer and autumn, so long as its 
services are required, is one of those wise and bene- 
ficent provisions, which cannot but excite our ad- 
miration.” * 
If we compare the myriads of caterpillars that 
often attack our cabbages and brocoli, with the small 
number, comparatively, of butterflies of this species 
that usually appear, we may conjecture that they are 
commonly destroyed in some such proportion,—a 
circumstance that will lead us thankfully to ac- 
knowledge the goodness of Providence, in providing 
such a check to prevent the total destruction of 
some of our most useful and esteemed culinary 
plants. 
The larva of the Large Cabbage Butterfly ap- 
pears in spring, and, indeed, throughout the greater 
part of the summer, as there are two or more broods 
every year. 
The chrysalis is of a rich yellow, clouded with 
gray, and speckled with crimson dots. 
The appearance of the Large Cabbage Butterfly 
on the wing, in a morning, is considered generally 
as an unerring prognostic that the weather will 
clear up, and the day eventually prove fine.
