Excerpt from Insects Injurious to Forest and Shade Trees

The larva obtains its food from the small vegetable radicals that everywhere per vade the fertile earth. It takes its food from the surface of' these roots, consisting of the moist exudation (like animal-perspiration), for which purpose its rostrum or snout is provided with three exceedingly delicate capillaries or hairs, which project from the tube of the snout and sweep over the surface, gathering up the minute drops of moisture. This is its only food. The mode of taking it can be seen by a good glass. Prairie Farmer, December, 1851.
