CABBAGE. 
Large White Cabbage Butterfly. Pieris brassice, Linn. 
Green-veined White Butterfly. Pieris napi, Linn. 
PIERIS BRASSICH.—1, butterfly; 2, eggs; 3, caterpillar; 4, chrysalis. 
The caterpillars of the white Cabbage butterflies are amongst the 
most common pests that we have in garden Cabbage growing; but in 
field cultivation they are much less troublesome (or at least very rarely 
reported), probably because it is the habit of the three common kinds 
for the caterpillars, when about to turn to chrysalids, to choose some 
sheltered spots, such as under eaves, or bars of fences, or amongst 
boards, or in sheds, &¢., which are not so conveniently at hand for the 
caterpillars to creep to in the fields as in garden cultivation, and 
consequently there are much greater numbers of butterflies to be 
found on garden than on field Cabbage. 
From some of the agricultural enquiries sent last year, it seems 
possible that, though the butterflies are well known, some notes on 
the life-history, and especially how to recognise the caterpillars, may 
be serviceable for field use; also a few notes bringing such treatment 
as is known quite up to date. 
On June 30th I received a letter from Mr. S. B. Burroughes, of 
Cley-next-the-Sea, Norfolk, in which he alluded to the above point,— 
of the caterpillars being most observable in gardens,—as follows :— 
‘Enclosed I beg to hand you a caterpillar, of which I found a 
lot in some Cabbages I am growing for next spring use. I do not 
remember having seen the like before,—not in a field; I have seen 
similar ones feeding on leaves in my garden.’’—(S. B. B.)
