Whence arises this mortality, which mows down the whole of my wasps? They have not suffered from [[156]]famine: they have not suffered from cold: they have not suffered from home-sickness. Then what have they died of?

We must not blame their captivity. The same thing happens in the open country. Various nests I have inspected at the end of December all show the same condition. The vast majority of Wasps must die, apparently, not by accident, nor illness, nor the inclemency of the season, but by an inevitable destiny, which destroys them as energetically as it brings them into life. And it is well for us that it is so. One female Wasp is enough to found a city of thirty thousand inhabitants. If all were to survive, what a scourge they would be! The Wasps would tyrannise over the countryside.

In the end the nest itself perishes. A certain Caterpillar which later on becomes a mean-looking Moth; a tiny reddish Beetle; and a scaly grub clad in gold velvet, are the creatures that demolish it. They gnaw the floors of the various storeys, and crumble the whole dwelling. A few pinches of dust, a few shreds of brown paper are all that remain, by the return of spring, of the Wasps’ city and its thirty thousand inhabitants. [[157]]

I

THE YOUNG SITARIS

The high banks of sandy clay in the country round about Carpentras are the favourite haunts of a host of Bees and Wasps, those lovers of a sunny aspect and of soil that is easy to dig in. Here, in the month of May, two Bees, both of them Mason-bees, builders of subterranean cells, are especially abundant. One of them builds at the entrance of her dwelling an advanced fortification, an earthly cylinder, wrought in open work and curved, of the width and length of a man’s finger. When it is peopled with many Bees one stands amazed at the elaborate ornamentation formed by all these hanging fingers of clay.
