“What pattern that she carries in her mind guides her scissors?”
Well, the Leaf-cutting Bee is even less well off than ourselves. She has no mental picture of her pot, because she has never seen it; she is not able to pick and choose in the crockery dealer’s heap, which acts as something of a guide to our memory by comparison; she must, without hesitation, far away from her home, cut out a disk that fits the top of her jar. What is impossible to us is child’s play to her. Where we could not do without a measure of some kind, a bit of string, a pattern or a scrap of paper with figures upon it, the little Bee needs nothing at all. In housekeeping matters she is cleverer than we are.
The insect excels us in practical geometry. I look upon the Leaf-cutter’s pot and lid as an addition to the many other marvels of instinct that cannot be explained by mechanics; I submit it to the consideration of science; and I pass on.
CHAPTER VII
THE COTTON-BEES AND RESIN-BEES
There are many Bees who, like the Leaf-cutters, do not make their own dwellings, but use shelters made by the work of others. Many of the Osmia-bees seize the old homes of the Masons; other honey-gatherers use earthworm galleries, snail-shells, dry brambles which have been made into hollow tubes by the mining Bees, and even the homes of the Digger Wasps burrowed in the sand. Among these borrowers are the Cotton-bees, who fill the reeds with cottony satchels, and the Resin-bees, who plug up snail-shells with gum and resin.
There is a reason for such arrangement. The Bees who work hard to make their homes, such as the Mason-bee, who scrapes hard clay and makes a large cement mansion, the Carpenter-bee, who bores dead wood to a depth of nine inches, and the Anthophora, who digs corridors and cells in the banks hardened by the sun, have no time left to spend in furnishing their cells elaborately. On the other hand, the Bees who take possession of ready-made homes, are artists in interior decorations. There is the Leaf-cutting Bee, who makes her leafy baskets with such skill; the Upholsterer-bee, who hangs her cells with poppy-petals, and the Cotton-bee, who makes the most beautiful purses of cotton.
We have only to look at the Cotton-bee’s nests, to realize that the insect who makes these could not be a digger, too. When newly-felted, and not yet sticky with honey, the wadded purse is very elegant, of a dazzling white. No bird’s-nest can compare with it in fineness of material or in gracefulness of form. How, with the little bales of cotton brought up one by one in her mouth, can the Bee manage to mat all together into one material and then to work this into a thimble-shaped wallet? She has no other tools to work with than those owned by the Mason-bees and the Leaf-cutting Bees; namely, her jaws and her feet. Yet what very different results are obtained!
