ATTACKING THE LEAVES. 349 



When the larva has attained its full size^ it draws together 

 the edges of a leaf half-way or more, and, forming a slight 

 net-work of silken threads, changes to a chrysalis of a dark 

 olive-green color, with a pale-greenish abdomen, a row of 

 black dots down the back, and another on each side, from 

 which in about ten days or a fortnight the perfect insect 

 appears. 



The moth (Fig. 362) is a native of America ; it flies by 

 day, and may often be seen on the wing about opening^^ in 

 the borders of the forest. Its 

 wings are yellow, varying in ^ 



shade from deep to pale, with 

 dusky spots and dots sometimes 

 few in number, while in other 

 specimens they are very numer- 

 ous, the larger ones being so ar- 

 ranged as to form an imperfect 

 band across the wings. The 



under side is usually a little deeper in color than the upper, 

 and, when the wings are expanded, they measure nearly an 

 inch and a half across. 



In its native haunts the larva probably feeds on the wild 

 currant, gooseberry, and strawberry. Although a common 

 insect, this is rarely complained of as injurious; should it 

 become so, the remedies recommended for No. 181 w^ould no 

 doubt be found efficient. 



No. 211. — The Currant Amphidasys. 



AmpJiidasys cognataiia Guenee. 



The larva of this insect is also a measuring-worm or looper, 

 and, although seldom found in sufficient numbers to prove 

 destructive, instances are on record where currant-bushes have 

 been almost stripped of their leaves by them. The larva,, 

 when full grown, is about two inches long, and may, when 

 not feeding, usually be found clinging to one of the leaves 

 or branches by its hind legs, with its body extended straight
