even following them into their shells and eating them 
there. It has a kind of brush which is used to put aside 
the slimy matter given off by the animal. 
Thus we see that not all insects are injurious to plant 
life. The majority, however, are decidedly so, and ener- 
getic methods should be taken to prevent attacks, or when 
attacks are made to destroy the insects before they are 
able to increase. 
Cabbage Butterfly. — This is a most destructive 
insect to all plants of the Cabbage tribe. The large white 
butterfly or imago is 
known to everyone, as 
are also the green larvae 
which devour at a great 
rate the leaves of the 
plants. They will con- 
ceal themselves in the 
curd of Cauliflowers, 
from which place it is 
very difficult to dislodge 
them. When they have 
made their full growth they get away into some sheltered 
corner and change themselves into pupae. These pale- 
green pupae, spotted with black, may be seen attached 
by the tail, and by a cord round the body, to the wall, 
fence, or other place where they have found shelter. To 
check these pests the young plants may be drenched with 
soapy water or dusted over with lime and soot. If in 
small numbers, the plants may be gone over and the 
caterpillars picked off and destroyed. 
Onion Fly. — This is another most troublesome insect.
