smooth surface of which the insects roll freely, and it is not affected 

 by wet weather. A closed box at the bottom receives and holds the 

 insects, and the jarring is easily performed on all parts of the tree 

 by means of a small mallet on the end of a pole. 



CURRANT WORM (p. 156). There are three distinct insects 

 which commit depredations on currant and gooseberry leaves, 

 namely, the Currant Span Worm, which comes out in the form of 

 a miller or moth, the Imparted Currant Worm, and the Native 

 Currant Worm, both of the latter forming four-winged flies in the 

 perfect state. 



The Currant Span 

 Worm (Ellopia ribe- 

 arid) is represented in 

 the following figure 

 (Fig. 498), the natural 

 size and appearance. It 

 is about an inch long, 

 bright yellow, with nu- 

 merous black spots. 

 The head is white, with 

 eye-like spots. It de- 

 vours the early leaves of 

 the gooseberry and cur- 

 rant, and when about to 

 change, hides under 

 rubbish, clods, or de- 

 scends into the ground 

 and changes to the 

 chrysalis, No. 3. In 

 two weeks it comes out 

 in the form of a moth 

 or miller, of a dull yel- 

 lowish white, with dark colored spots towards the ends of the wings. 

 The spread wings measure about an 

 inch and a quarter. The figure (Fig. 

 499) represents its appearance, but is 

 too dark. Where the larva? have been 

 numerous, and have stripped the cur- 

 rant row, this miller may be often seen 

 in considerable numbers, flying over
