The GraOC Lcaf- folder, Desmia funeralis (Des'mi-a fu-ne-ra'lis) is a common species, the larva of which feeds on the leaves of grape. The larva folds the leaf by fastening two portions together by silken threads. When full grown, it changes to a pupa within the folded leaf. The moth is black with shining white spots. The male (Fig. 273) differs from the fe- male in having a knot-like enlargement near the middle of each antenna. There is some variation in the size and shape of the white spots on the wings. In some specimens the white spot of the hind wing is sepa« rated into two or three 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 Comstock, John Henry, 1849-1931; Comstock, Anna Botsford, 1854-1930. joint author.
