tion of the strawberry over large areas, and which would prcjbablv liave done 

 so, for a considerable time, at least, if measures of controlling it had not hap- 

 pily been hit upon. 



The following description is by Prof. Kiley, and is extracted from the 

 American Entonwlugist for January, 18G9: — 



" The larva or caterpillar measures, Avhen lull grown, a little more than 

 one-third of an inch. It is largest on the front segments, tapering slightly 

 towards the hinder ones. In color it varies from a very light yellowish

brown to a dark olive-green or brown, with a body soft and somewhat semi- 

 transparent. Its head is of a shining yellowish brown color, wdth a dark eye- 

 spot on each side. The second segment has a shield above, similar in color 

 and appearance to the head, and on each segment or ring of the body are a 

 few pale spots, from each one of which arises a single hair. The hinder seg- 

 ment has two black spots, while the under surface, feet, and forelegs are about 

 the same color as the body above. In certain parts of Northern Illinois and 

 Indiana this insect has been ruining the strawberry beds in a most whole- 

 sale manner. It crumples and folds the leaves, feeding on their pulpy sub- 

 stance, and causes them to appear dry and seared. It most usually lines the 

 inside of the fold with silk. There are two broods during the year, and the 

 worms of the first brood, which appear during the month of June, change to 

 the pupa state within the rolled-up leaf, and become moths during the fore 

 part of July. 



"The moth has the head, thorax, and fore wings reddish brown, the latter 

 streaked and spotted with black and white; the hind wings and abdomen 

 are dusky. The wings, when spread, measure nearly half an inch across. 

 After pairing, the females deposit their eggs on the plants, from which eggs, 

 in due time, there hatches a second brood of worms, which come to their 

 growth towards the end of September, and changing to pupte. pass the win- 

 ter in that state." 



Observations made at Normal show that considerable numbers of the larvje 

 winter over. The moths begin to fiy very early in spring, the first warm 

 days of the opening season calling them forth. 



The favorite remedy for this pest is that of mowing the field after the ber- 

 ries are picked, and burning it over when dry. The plants are not hurt, and 

 the leaf-roller is checked at once, and in two or three years reduced to insig-
