placed in a breeding cage, with fresh growing clover plants which had 
been carefully transplanted and kept in growing condition. In the 
heads of this last planting larve were found on August 15. 
From these experiments it may be concluded, so far as conclusions 
can be drawn from a single series of experiments, that the eggs may be 
deposited on the plants in the field, and thus the larve be drawn to the 
stack or mow; and, also, the eggs may be deposited in the stacks in the 
field early in August. The prospect of protecting the hay from attack 
certainly does not look very encouraging, nor is the outlook for assist- 
ance of parasites much more favorable, as I have not reared a single 
Species that was clearly parasitic on the hay worm. 
Mr. W. B. Hall, writing from Wakeman, Huron County, Ohio, 
states that these worms have been very troublesome, especially in his 
barn. A straw tick left on old hay in one of his mows was thickly 
covered with cocoons during May and June. Under date of June 29, he 
mentions observing the moths, at that time in considerable numbers, 
especially about straw stacks and straw sheds. The fondness of this 
insect for old, compact masses of hay is well known, but it seems very 
doubtful about this being their exclusive habitat during summer, or 
that a careful burning of all old stack bottoms, etc., would secure im- 
munity from the fall and winter attacks of the pest.
