Página 383 - That for many years it has been one of my constant regrets that no schoolmaster of mine had a knowledge of natural history, so far at least, as to have taught me the grasses that grow by the wayside, and the little winged and wingless neighbors that are continually meeting me with a salutation I cannot answer as things are.

Página 292 - As soon as vegetation starts in the spring, the mature bugs which winter over in all manner of sheltered places may be seen collecting on the various plants which have been mentioned.

Página 22 - They possess the additional bad habit of gnawing into the stems of the clusters of the grapes, which either wilt or drop off. The eggs, which are 0.05 inch in diameter, perfectly round, and of a uniform delicate yellowish-green color, hatch Fig. 44. — Ampelophaga myron Cram., caterpillar.

Página 44 - In 1860 — the year of the great drouth in Kansas — the corn crop in that State was almost entirely ruined by the Corn-worm. According to the "Prairie Farmer," of January 31, 1861, one county there which raised 436,000 bushels of corn in 1859, only produced 5,000 bushels of poor wormy stuff in 1860, and this, we are told, was a fair sample of most of the counties in Kansas. The damage done was not by any means confined to the grain actually eaten by the worm; but...
Página 80 - I have preserved my 434 cabbages, but I have visited every one of them daily now for four months, finding on them from thirty-five to sixty full-grown insects every day, some coupled and some in the act of depositing their eggs. Although many have been hatched in my garden the present season, I have suffered none to come to maturity; and the daily supplies of grown insects that I have been blessed with, are immigrants from some other garden. " ' The perfect insect lives through the winter, and is...
Página 361 - Under these scales 1 have repeatedly met with a small maggot, three-hundreths of an inch long, or frequently much smaller, of a broad oval form, rounded at one end and tapering to an acute point at the other, soft, of a honey-yellow color, slightly translucent and shining, with an opaque brownish cloud in the middle, produced by alimentary matter in the viscera, and divided into segments by faintly impressed transverse lines.
Página 131 - Having taken a strong hold on the fruit the female makes a minute cut with the jaws, which are at the end of her snout, just through the skin of the fruit, and then runs the snout under the skin to the depth of one-sixteenth of an inch, and moves it back and forth until the cavity is large enough to receive the egg it is to retain. She next changes her position, and drops an egg into the mouth of the cut...
Página 262 - After the first moult, they are characterized principally by two pale-yellowish subdorsal lines, which border what was before the dark line above described. After the second moult, which takes place in about a week from the first, the characteristic pale spots on the back appear, the upper pale line becomes yellow, the lower one white, and the space between them bluish: indeed, the characters of the mature larva are from this period apparent. Very soon they undergo a third moult, after which the...
