EXPERIMENT STATION BULLETINS. 



401 



English periodical (Entomologist's Monthly Magazine, Vol. XIV, pp. 200- 

 "204) we find all the early stages fully described. This species was bred on 

 the leaves of boneset (Eupatorium), and was also taken on hedge 

 nettle (/S/ac/it/s) and strawberry leaves, 

 brooded. 



DESCRIPTION 



It is thought to be two or more 



The full grown larva is nearly an inch in length. Head and thoracic 

 shield drab, with black markings as shown in the drawing. Along the 

 body is a dark green dorsal line on each side of which is a very faint 

 almost obscure opaque white line merging off to a translucent greenish 

 and bordered by another opaque white line. On the sides is a very obscure 

 yellowish green line. There is a distinct caudal shield of white and dark 

 green. The caterpillar is sparsely covered with hairs. 



The moth is reddish brown on the front wings and a grayish brown on 

 the hind wings. Both have the faint black markings shown in the 

 drawing. 



REMEDY. 



It is probable that the usual habit of this caterpillar is to draw the leaves 

 together and feed on the leaves rather than bore in the stem. When feed- 

 ing on the leaves alone it does much less harm. At present the species is 

 not plentiful enough to cause any immediate alarm. Were the life history 

 of the species better known, it is probable that some good means of control 

 could be found.
