NATURAL HISTORY OF INSECTS. 



PLUME MOTHS (Pterophoridx) . These Moths are mostly of 

 a small size, and may easily be recognized as they have the 

 fore-wings once or twice notched or cleft at or near the base; 

 their hind wings are twice-cleft. 



Fig. 227. 



The caterpillars usually live exposed upon the leaves of 

 plants ; they are thinly covered with short, stiff hairs, and are 

 provided with sixteen legs. When about to shed their larva- 

 skin and change to paupa?, they fasten themselves to some 

 object by the underside of the hind part of the body. The 

 chrysalids generally are angular and sparsely hairy. 



The specific names of these insects usually end in dactylus. 



The Grape Plume-moth (Fig. 227), is an example of this 

 Family.
