INSECTS INJURIOUS TO THE APPLE 



Indian Euphoria (Euphoria inda Linn.) . It is about one-half of 

 an inch long and is heavy-bodied. The wing covers are yellowish 

 brown, marked with irregular darker patterns. The head and 

 thorax are blackish, or a dark copper brown, thickly covered with 



short yellowish hairs. The 

 under side of the body is 

 black and hairy (Fig. 131). 

 The beetle moves slowly and 

 is not easily disturbed. 



Eggs are deposited in 

 manure heaps or decaying 

 vegetable matter or in sod. 

 In midsummer the grub 

 changes to a pupa beneath 

 the surface, the beetles 

 emerging in the early au- 

 tumn. There is one brood a year. The adults eat ripening apples 

 and are sometimes also found on green corn. 



Control. Where troublesome, hand-picking may be resorted 

 to, or the beetles may be attracted to a pile of decaying fruit and 

 destroyed. This is not regarded as a serious pest, but is fairly 

 abundant in localities.
