THE STRAWBERRY WO^W—Emphytus maculatus Norton, 



[Ord. Hymenoptera ; Fam. Tenthredixid.e.] 



In connection with the foregoing account of the Imported and 

 Native Currant Worms, it will be well to give the history and habits 

 of a worm of the same family, which is the most conspicuous, if not 

 the most common defoliator of that more profitable and more gener- 

 ally cultivated fruit — the Strawberry. This is the Strawberry Worm 

 {Emphytus rnaculatus Norton) the natural history of which was first 

 given by myself in the Prairie Farmer for May 25, 1867. 



The species appears to have a wide range, as I have met with it 

 in many parts of Illinois and our own State, have received it from 



Iowa, and it is reported from 

 various sections in the East 

 and from Ontario. In 1874, 

 Prof. Bessey, of the Iowa Ag- 

 ricultural College, reported it 

 as devouring the Strawberry 

 plants in many parts of that 

 State, and Mr, HofFmeister, of 

 Fort Madison, wrote me that 

 in many sections the plants 

 had to be plowed under in

may be seen hanging to, and flying about the vines, in fields which 

 have been previously infested. They are dull and inactive in the cool 

 of the morning and evening, and at these hours are seldom noticed.
