This disparity is maintained, in more or less marked proportions, whatever the species of the bee invaded. In the cocoons of the Mason bee of the Sheds, I discover the average proportion to be six females to one male; in those of the Mason bee of the Walls, I find one male to fifteen females.
This has been so often said and so clearly shown that I should consider it unnecessary to repeat it had not my attention been called to the fact that the success of several people and associations in the United States in raising cocoons has again made it a temptation to endeavor to reel silk, and during the past year I have received applications from people in different States for information as to the kind of silk reel employed here which would be most suitable for use by them.
We saw the whole process, from the sorting of the yellow and white cocoons to the huge bolts ready for the market, while one of our smiling hosts significantly remarked, "The yellow and white blend very nicely together."
Andrew Idlewine, I now had a complete Cecropia history; eggs, full-grown caterpillars, twin cocoons, and the story of the emergence of the moths that wintered in them. I do not suppose Mr.
It must therefore, one would think, form a somewhat highly seasoned diet. The beetles, however, delight in it. No matter how many flocks I provide them with, they are all consumed. But no one, that I know of, has ever found the Golden Gardener and its larva in the silken cocoons of the Bombyx. I do not expect ever to make such a discovery.
In a certain gravel-pit in the neighbourhood, with vertical walls visited by the sun, I have been able within a short space of time to collect enough to fill the hollow of my hand completely. They differ from the cocoons of the preceding species only in their smaller size. The provisions consist of young Acridians, varying from about a quarter to half an inch in length.
Land is very much dearer, and taxes are higher in the European silk districts than with us, and every little crop of cocoons has to pay its share, which adds a considerable percentage to its cost. The buildings possessed by peasants and used for the raising of silk worms are, in general, small, close, and miserable.
A minute description seems useless to me in the type of investigation which I am pursuing. Her burrows, very close to one another when an easily-worked vein presents itself, afford an ample harvest of cocoons once the site is discovered.
Once the partition is pierced, they attack the dead cocoons, go right through them, reducing the dead grub, now dry and shrivelled, to dust, and at last emerge, after wrecking everything in their path. The dead cocoons, therefore, are not spared; they are treated as would be any other obstacle capable of attack by the mandibles.
For encouragement and assistance in the undertaking, they were willing to engage persons from Italy, acquainted with the method of feeding the worms and winding the thread from the cocoons, to go over with the settlers, and instruct them in the whole process.
