The Brown Fruit-chafer {Euphoria inda Linn.). — The ears 

 of green corn, ripening fruits and some flowers are subject to

 the contents of the abdomen. Transformation to pupa takes 

 place in a cocoon smooth within and irregular on the outer 

 surface. This species occurs practically everywhere in the 

 United States east of the Rocky Mountains.

 overripe or injured fruits or other vegetable growth, and

 within. The beetles devour flowers of different fruits, and
