Economic entomology for the farmer Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; economicentomol00smit Year: 1906 3o6 AN ECONOMIC ENTOMOLOGY. black markings are so reduced as to be scarcely visible, except on careful inspection. The caterpillar, which is green and nar- rowly striped, feeds on clovers, and, while abundant, is not prac- tically harmful. Among the pets of the lepidopterist are the species of Catocala, a series of large moths with the hind wings black, or yellow and red banded with f*''^- -W- black. We have a great number of species, and while the hind wings are so prominently col- ored and marked, the fore-wings are mottled gray, brown, and black. They rest exposed during the day up- on the bark of trees, entirely invisible because so closely resembling their surroundings, the gaudy hind wings being com- pletely covered by the modest fore-wings. While some of the caterpillars feed upon cultivated plants, especially the plum, they are never abundant enough to attract attention. Last in the Noctuids we have the 'snout-moths,' or deltoids, the latter term applied from the fact that when the insects are at rest the outline bears somewhat a re- semblance to the Greek letter delta J. The species are recognizable without much trouble by the unusually long palpi, which in many cases point directly forward and form a decided snout. The only species that has occurred in num- bers justifying the term injurious is the Hypena huimili, the caterpillar of which —a slender green creature—feeds upon hops. Within my experience it has never been sufficiently troublesome to make insecticides necessary ; but should it ever Catocala uUronia and its larva. Fig. 348.
