THE NATIONAL GEOGRAPHIC MAGAZINE JAPANESE BEETLES DINE ON A PEACH At the beginning of the season the beetles attack the fruits prematurely ripening because of infestation by other foes, but later they turn their attention to the sound peaches, apples, etc. As many as 278 beetles have been removed from a single fruit.

By 1919 they had become so thick that one person could collect as many as 20,000 in 12 hours. During a recent season an average of one and one-third gallons of beetles were shaken from each of 156 ten-year-old peach trees, all of which seemed as full as ever 24 hours later. An average of 175 larvae were found in each square yard of a New Jersey pasture.
