■^riioso iiistH'ts. wiiich aro closely rolutod to the <'0(llin<? moth 

 and the iipplo troo loaf rollors, which aro so hannfiil to our or- 

 chards in Oiifly summer, are all found in Michi<ran and the other 

 >»orthern States, and South even to the (lulf. While they at- 

 tack all the clovers they are not contined to them, hut work on 

 nniny other garden and field plants. In rll the species the larvae 

 draw the leaves ahout them by means of silken threads, which 

 they spin, and when disturbed drop and hang suspended by 

 means of a thread, which, like a spider, they can spin as needed. 

 A more harmful leaf roller attacks the clover seed, and will be 

 described later. 



The larva of the first species is yellowisli-green, the second 

 green, the third yellow. The larva* are about \ of an inch (13 

 to 14 m m) long. The pupai are shorter and brown in color. 

 The moth of the first species is bright yellow, with x* v-shapeJ 

 purple bands on each front wing. The same color marks the 

 front and outer nnirgins of the same wings. The back, or sec- 

 ondary wings, are yellowish, varying to brown. It e.\[)and8 a lit- 

 tle more than 4 of an inch. The second species is a little larger^ 

 The males are dark brown, with reddish-yellow nuirkings. Hind 

 wings reddish. Females red, with oblique obscure bands across 

 front wings. Females expand J of an inch. The males are not 

 quite so large. The color of the moth in the third species varies 

 from yellow to yellowish-browu. It is about the size of the sul- 

 fureana. 



These are seen feeding on the rolled up leaves, which servo both 

 for home and food in May and June, and again in Augast, so 

 there are two broods a year.
