THE FOOD HABITS OF SOME APHROPHORA LARVAE. 



E. D. Ball. 



The larvae of all the American species of the Family Cercopidae 

 as far as known envelope themselves in a frothy mass. Contrary to 

 popular opinion and to most of the published accounts this froth 

 does not issue as bubbles from the body of the insect, but is made 

 by pushing the tip of the abdomen up out of the froth and grasping, 

 with the anal appendages, a bubble of air and bringing it down and 

 releasing it within a liquid film. This liquid film is simply the ex- 

 cretion from the alimentary canal of the sap which is imbibed by 

 these insects in large quantities. This copious liquid excretion is a 

 common occurrence in other families of the Homoptera. In the 

 Plant Lice (Aphidae) it gathers in drops and is called " Honey Dew." 

 The Leaf Hoppers and Tree Hoppers expel a clear liquid with some 

 force. In some species this is in sufficient amount so that when the 

 insects are numerous the foliage may drip, producing the " Weeping 

 trees " of the Southern States.
