"Of the two forms of pitcher in this genus the larger and ordinary form, that of the adult plant, is somewhat twisted, and instead of a lid has a large inflated hood overarching the small mouth. A large bilobed nectariferous and brightly colored expansion hangs down from this, and attracts insects, particularly moths. As in Sarracenia, the plant seems merely to absorb the products of their putrefaction." — The Encyclopedia Britannica, 1893

Also known as the Seventeen-Year Locust, derives its specific name from the fact that it makes its appearance in certain districts at stated intervals of seventeen years in immense numbers, when the millions of them, swarming on the forest and fruit trees, almost deafen the observer with their trilling calls to the female, and form an abundant feast to the swine, fowls, and wild animals on the land, and if near a river or lake, to the fishes in the water.

Also known as the Cotton-plant louse, is a great nuisance to the planters, especially when the plants are very small, as then they are more liable to succumb to the attacks of these insects, as by sucking out the sap they distort the stems, and in fact frequently kill the plants before they have attained sufficient maturity and strength to withstand their repeated attacks.

Eriosoma Lanigera, or the Wooly Apple-Tree Blight. These insects appropriate for their generic name two Greek words, signifying wool and body, the insect being partially enveloped in a cottony or wool-like secretion, furnished from its own body. The eggs are deposited in crotches or cracks of the branches or bark, often at or near the surface of the ground, or on new shoots springing from the parent tree.

From the well known nocturnal habits of moths, and the certainty of their being destroyed by a light, a cheap and effective mode of destroying them, shown in the annexed figure. It consists of a pan of viscid matter placed upon a stake, which is set in the field of cotton at suitable distances. A block of wood is placed in the center of the pan, upon which is placed a lighted glass lantern. The moths, being attracted by the light, dash against it and fall into the pan, and are thus destroyed before depositing their eggs upon the tender leaves of the growing plant.

The rear end of the machine is mounted upon two wheels. A trough, with a runner-like bow, containing some adhesive matter, is suspended upon each side of the row. A vibrating arm or beam, carrying wisps or brushes, is adjustably suspended form the farm, and as the machine is pushed along the row of plants the insects are shaken into the troughs, from which they are unable to escape.

The females deposit their eggs, which are small, oval, and black, on twigs and bark in the autumn; the insect is hatched out the next spring, and feeds upon the sap of the tree. The first broods are all females, which in a short time, without any intercourse with the males, give birth to living young by the process of gemmation. These also produce other young ones, which are all females as long as the summer lasts, and it is only in the autumn that males are produced, which, uniting with the females, become the parents of the eggs for the following spring brood, thus bearing living young all the summer, and laying eggs which can withstand the frosts of the winter in autumn for the following spring season, while the parent insects in winter are destroyed by the wet and cold weather and alternate freezing and thawing.

Pediculus Pubis. The crab-louse is gray-black and is a much broader square form than the other two species of louse, that has been a great scourge to soliders in time of war. This insect has been named the crab-louse from its broad crab-like appearance. It is of grayish color; the head is small, and appears to be united with the broad body without any thorax; it inhabits the hairy part of the body, under the arms or shoulders, in the beard, etc., but appears to avoid the head. These insects pierce deeply into the skin of mankind, and produce an intolerable itching.
