Annual report of the North Carolina Agricultural Experiment Station . FlG. 8.—Ear of corn from which several generations of the Angoumois Grain Moth haveemerged—slightly reduced. 16 N. C. AGRICULTURAL EXPERIMENT STATION. measure across the expanded fore wings a little over one-half front wings bear a fringe of long hairs on the anal edge, and thehind wings bear a continuous border of the same. The moths are verydelicate, easily crushed and readily killed by poisonous Fig. 9.—The Angoumois Grain Moth; a, female; b, male; c, male with wings expanded—all two and one-half times natural size. The larva (Fig. 10, b) is white, distinctly segmented and attains alength of about one-quarter of an inch. The jaws are brown andhorny. When grown the larva transforms to a light-brown pupa (, c) in its feeding place, but provides beforehand for the escape ofthe adult by leaving over its burrow only a thin skin of the grain,through which the moth easily manages to escape.
