The larvae feed on the roots and stalks of grasses, living in little tubes constructed of bits of earth and vegetation fastened together with silk. Several spe- cies are sometimes quite injurious to young corn planted on land where they have been abundant, the most common being known as the corn-root web-worm. Two other families of this group are known as plume-moths (Ptcro- phoridac and Orucodidac], as the wings are split into parts looking like a small fan of feathers. The larvae of one species occasionally webs up the terminals of young grape shoots, and another species is sometimes common on sweet-potato vines, but they are rarely of economic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sanderson, Dwight, 1878-1944; Jackson, C.
