In most species the fore wing is separated into two parts, by a fissure extending about one half the length of the wing; while the hind wing is divided into three parts by fissures extending farther towards the base of the wing.

In most species the fore wing is separated into two parts, by a fissure extending about one half the length of the wing; while the hind wing is divided into three parts by fissures extending farther towards the base of the wing. Sixty species belonging to the family have been found in North America. One of our most common species is the Gartered Plume, Oxyptiltisperiscelidactylus (Ox-yp'ti-lus per-is-cel-i-dac'ty-lus). This is a small moth, expanding about seven tenths of an inch. It is of a yellowish brown color marked with dull whitish streaks and spots (Fig. 284). The larvae hatch early in the spring, and feed upon the newly-expanded leaves of grape. They fasten together several of them, usually those at the end of a shoot, with fine white silk; between the leaves thus folded the cater- pillars live either singly or two or three together. They become full grown and change to pupae early in June. The pupa is not enclosed in a cocoon, but is fastened to the lower side of a leaf by its tail by means of a few silken threads, in nearly the same way that the chrysalids of certain butterflies are suspended. The pupa state lasts about eight days. Family ORNEODIDiE (Or-ne-od'i-dae). The Many-plume Moths. These insects resemble the Plume Moths in having the wings fissured ; but here the fissuring is carried to a much greater extent than in that fam- ily, each wing being divided into six plumes (Fig. 285). As yet only a single species of this family has been found in North Amer- ica. This is Orneodes hexadactyla (Or- ne-o'des hex-a-dac'ty-la)..
