The wire worm coming forth, feeds on the roots of grass. They nia)- be found in an}- of our tame and wild grasses, but they are seldom found here in sufficient numbers to make a very great impres- sion on the appearance of the grass lands. However, when the grass land is broken up and the comparative number of plants which the field con- tains is few, as with corn, the wire worms have to concen- trate their labors more on the individual plants, and then it is that their presence is felt, the damage being- done not only to the corn ])lants, but not uncommonly the seed is attacked and de- stro3^ed before the j^oung ])lant can present itself. The wire worm attacks the corn kernel either before or after it has sprouted and not in- frequently will a kernel be found into which the wire worm has made an entrance. The roots of the plant are seriously injured, the smaller roots are often eaten away, while the larger ones are bored and fre- quently this boring is done through the underground part of the stalk. The total destruction of the plant generally results. This larval stage lasts for two years. The pupating occurs in July or August, and in the course of three or four weeks a reddish beetle comes forth, known as the "click beetle," commonly remembered by the clicking sound and sudden springing of the beetle when placed upon its back. The beetle may either remain in the ground during the winter or may come to the surface, passing the time in sheltered places. This is the beetle that lays the eggs from which comes the brownish colored larva (wire worm) mentioned above. Other cereals are attacked by this pest, as are also some of the root crops. It bothers wheat, rye, barley, oats, timothy, clover, etc.; and may be found attacking potatoes, turnips, beets, cabbage, onions, and
