This is an interesting insect, in a scientific point of view, but it 
has not multiplied, as yet, to a sufficient extent to make it of much 
practical importance. Its solitary habits, that is its mode of feed¬ 
ing separately, or not in flocks, would render it a troublesome in¬ 
sect to contend with should it ever become very numerous. The 
only method that suggests itselt to us-, at present, of destioyin^ 
them, is by the common practice of hand-picking, or shaking then 
from the trees and crushing them under foot. 
The following cut, made at the office of the Prairie Farmer, ex 
Inbits another view of these caterpillars, both in their natural siz< 
and magnified.
