The Pupa—Shortly after becoming full grown the larva leaves the apple and seeks some protected spot in which to hide while passing through its transfor- mations from larva to pupa, then to moth. Having found a suitable place, it hollows out a little oval cavity with its jaws and proceeds to envelop itself in a thin tough cocoon of silken threads in- termingled with particles of the excavated material. When completed, the cocoon is usually oval in form and about three- fourths of an inch long. When the pupal stage is reached the insect remains in that stage for about three weeks, and then emerges as the adult or moth. The Moth or Adult—The moths are really beautiful little creatures. The body is about three-eighths of an inch long and is of a modest greyish brown color. The fore wings when fully expanded measure about three-fourths of an inch from tip to tip and are of approximately the same color as the body but relieved by incon- spicuous, transverse wavy lines or lighter scales. The hind wings which are en- tirely covered when the insect is at rest are nearly slate colored and are clothed with long hairs. The most characteristic marking is a large golden brown spot at the posterior outer angle of each front wing. No other insect is known which has this marking and no insect need be mistaken for the codling moth. The males are further distinguished by a narrow pencil of black hairs on the hind wings and an elongated black spot on the upper surface of each front Fig. 1. Codling moth.
