June and July, and lays eggs on cured clover wherever it can be found. 
A second lot of moths are out in late summer. 
If the hay is used up clean each year, and any refuse is destroyed, 
there will be practically no injury. If there is likelihood that all will 
not be used by the next 
July, salt down the first 
two feet of hay when put- 
ting it up, using two 
quarts of salt to the ton. 
Do not place new hay on 
top of remnants of last 
year’s crop. The old hay 
should be removed and the 
mow thoroughly cleaned.
