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.
