THE GOOSEBERRY SPAN-WORM, 



(Eiifitchia ribearia, Pack.) 



This, which has been called the American Currant- 

 moth, and sometimes merely " Currant- worm," was first 

 described by Dr. Fitch, as Ahraxas ribearia, referring it 

 to the same genus with the European Gooseberry Moths. 

 Later, Dr. Packard finding it to belong to a diiferent 

 genus, dedicated it to its distinguished discoverer, call- 

 ing it EufitcTiia. While it is found upon the Gooseberry, 

 and Currant, it shows a decided preference for the 

 former, and when the two are growing near one another, 

 it will first attack the Gooseberry. 



It may at once be distinguished from any other worm 

 found either on Gooseberry or Currant, by its being 

 what is popularly called a Measuring-worm. Figure 123, 

 shows this larva, which, when full-grown, measures about 

 an inch, and is of a light-yellow color, with lateral white 

 lines, and numerous black spots and round dots. The 

 head is white, with two black eye -like spots on the outer 

 sides above, and two smaller ones beneath. The six 

 true legs are black, and the four pro-legs yellow. It at- 

 tains its growth about the middle of June, when it de- 

 scends to the ground, and either burrows a little below 

 the surface, or hides under any rubbish that may be lying 

 there; but in neither case does it form any cocoon. 

 Shortly after this it changes to a chrysalis, shown at the
