Genus ANCYLIS Hubner 



(i) Ancylis comptana Frolich. (The Strawberry Leaf- 

 Toller.) 



Syn. conjlexana Walker ; fragaritz Walsh & Riley. 



This little insect has proved a very destructive foe of the 

 strawberry in parts of the Mississippi Valley. There are two 

 broods annually. The insects roll up the leaves, and feeding 

 upon the tender paren- 

 chyma, cause the plants 

 to wither and dry. So

 the larvae proved in some 

 places that horticultur-

The insect is found in 



Canada and in the portions of the United States immediately

 Pennsylvania, no great loss from its attacks has as yet been re- 

 ported from this part of the country.

 This well-known and most destructive little insect is estimated 

 to inflict an annual loss upon the fruit-growers of America which 

 amounts in the aggregate to tens of millions of dollars. Every 

 one is familiar with the pinkish worm which is encountered at 

 the heart of apples and pears. But for every apple and pear
