INJURING THE HAY. 241 



natural size, at Fig. 130. The adult is a very pretty 

 little purple and golden moth (5, 6) which deposits 

 eggs upon such clover hay as it has access to. The 

 eggs soon hatch into small brown worms that become 

 full-grown (1, 2) in a few weeks. They then spin 

 silken cocoons (3) within which they change to 

 chrysalis (4), to emerge soon after as adult moths. 

 There are two or more broods each season. 



Remedies. — It will readily be seen that these in- 

 sects are more likely to prove troublesome when old 

 hay is left over from season to season for them to 

 breed in. Consequently hay mows should be thor- 

 oughly cleaned out each summer, and new stacks 

 should not be put on old foundations until all of the 

 leavings of the previous season are removed. Hay 

 which is thickly infested by the worms should be 

 burned.
