INJURING THE LEAVES.

Remedies. — This insect is seldom sufficiently nu- 

 merous to require remedial treatment. The larvse 

 may be crushed within their cases, or the cases picked 

 off and burned late in autumn, before the leaves fall 

 off, if they threaten to become seriously destructive. 



The Beautiful Wood-nymph. 



Eudryas grata. 

 This is a very handsome insect, both in its imma- 

 ture and adult stages. The moth (Fig. 60, g) meas- 

 ures nearly two in- 



ches across its ex- 

 panded front wings, 

 which are of a glos- 

 sy creamy - white 

 color, beautifully 

 marked with pur- 

 ple, brown a n d 

 green. It lays its 

 eggs (e,f) on the 

 under side of the 

 leaves. The larva? 

 soon hatch and feed 

 upon the foliage, 

 developing rapidly, so that by the latter part of sum- 

 mer they are full grown (a), the body being of a pale 

 bluish color, crossed by bands and lines of orange 

 and black. The larva? now leave the vine and seek 

 some concealed situation in which to pupate. They 

 pass the winter in the chrysalis state, and emerge 

 the following spring as moths.
