CLOVER DRASTERIA. 387 



I have found Paris green sure death to orchard and shade tree 

 leaf rollers, and without doubt it would kill these that infest the 

 clover. Its practicality however in this case is not so apparent. 

 It is to be hoped that parasites and other enemies will prevent 

 these leaf rollers from becoming very serious pests. 



Without doubt other Tortricids will be found to attack the 

 clover, but as all are so nearly alike in their character and habits, 

 what has been said will apply in a general way to all of them.

 This is as common as any moth in Michigan, and the same is 

 true in many other States. The familiar, short, jerky flight re- 

 minding us of the tiger beetles, is seen from early spring till late 

 autumn. Though so common, and though with slight excep- 

 tion (it sometimes feeds on grass) the caterpillars feed exclusively 

 on clover, yet I think the insect is not considered a foe to be 

 dreaded. It may be that in case of crops like the clover, where 

 plants are numbered by the million, we suffer more from insect 

 attack than we know. 



The larva is reddish-brown, marked with longitudinal lines of 

 dark, white and pink color. When full grown it is 3cm (1^ 

 inches) long. There are only three pairs of pro legs, so tlie cat- 

 erpillar, like others of the lower ISTootuids, is a geometer, or 

 "measuring worm." It spins a loose cocoon, in which, as also 

 in its gait, it reminds us of the 

 true geometers. The moth is 

 well represented in the figure. 



The fore wings are dusky-brown, ^ 



with darker bands crossing them, ^ fig 142 '^
