Economic entomology for the farmer Economic entomology for the farmer and fruit-grower economicentomolo01smit Year: 1906 The insect world. 299 We sometimes find boring in the stems of wheat, corn, pota- toes, and a great variety of other plants a yellowish-white cater- pillar with rather prominent black spots, furnished with little soft hairs and with a black head. This is the larva of another Noctuid moth, the Achatodes zece. It sometimes does consid- erable, though usually temporary, injury to the infested plants, and is kept in check, as a rule, by its natural limitations. The moth which produces this caterpillar is broader winged than the species previously mentioned, and the primaries are of a deep, somewhat mottled, red-brown. The outer margin is rusty red, especially towards the tip of the wing, and none of the other markings are well defined. The species has not, in my experi- ence, appeared in numbers large enough to make it necessary to adopt remedial meas- ures, and this is fortu- ^^^- 337- nate, because from its method of feeding it is somewhat beyond our reach. Occasionally we note upon grape-vines a smooth, greenish cat- erpillar with broken, rather inconspicuous, lateral lines. It attains a length of from one and one-half to two inches, and differs from the other greenish cater- pillars of the vine by lacking all trace of either horn or eye-spot on the last segment. It pupates a little below the surface, and in due time appears as a moth which is distinctly flattened, has the fore-wings of a mottled, dull, smoky brown, and the hind wings of a dull coppery hue. It is the Pyropliila pyramidoides, and may be occasionally found during the day hiding in crevices, or under bark, for which its flattened body adapts it unusually well. At night it is attracted to light, and occasionally becomes rather common, though rarely abundant enough to need remedial measures. When it does occur in numbers it is easily controlled Pyrophila pyraniidoides and its larva.
