The Wonders of Instinct: Chapters in the Psychology of Insects

The Beetles proceed to the burial of the hinder part of the Mole; they
twitch and jerk it now in this direction, now in that. Nothing comes of
it; the thing refuses to give. A fresh sortie is made by one of them to
discover what is happening overhead. The second ligature is perceived,
is severed in turn, and henceforth the work proceeds as well as could
be desired.
My compliments, perspicacious cable-cutters! But I must not exaggerate.
The lashings of the Mole were for you the little cords with which you
are so familiar in turfy soil. You have severed them, as well as the
hammock of the previous experiment, just as you sever with the blades
of your shears any natural filament which stretches across your
catacombs. It is, in your calling, an indispensable knack. If you had
had to learn it by experience, to think it out before practising it,
your race would have disappeared, killed by the hesitations of its
apprenticeship, for the spots fertile in Moles, Frogs, Lizards and
other victuals to your taste are usually grass-covered.
You are capable of far better things yet; but, before proceeding to
these, let us examine the case when the ground bristles with slender
brushwood, which holds the corpse at a short distance from the ground.
Will the find thus suspended by the hazard of its fall remain
unemployed? Will the Necrophori pass on, indifferent to the superb
tit-bit which they see and smell a few inches above their heads, or
will they make it descend from its gibbet?
Game does not abound to such a point that it can be disdained if a few
efforts will obtain it. Before I see the thing happen I am persuaded
that it will fall, that the Necrophori, often confronted by the
difficulties of a body which is not lying on the soil, must possess the
instinct to shake it to the ground. The fortuitous support of a few
bits of stubble, of a few interlaced brambles, a thing so common in the
fields, should not be able to baffle them. The overthrow of the
suspended body, if placed too high, should certainly form part of their
instinctive methods. For the rest, let us watch them at work.
I plant in the sand of the cage a meagre tuft of thyme. The shrub is at
most some four inches in height. In the branches I place a Mouse,
entangling the tail, the paws and the neck among the twigs in order to
increase the difficulty. The population of the cage now consists of
fourteen Necrophori and will remain the same until the close of my
investigations. Of course they do not all take part simultaneously in
the day's work; the majority remain underground, somnolent, or occupied
in setting their cellars in order. Sometimes only one, often two, three
or four, rarely more, busy themselves with the dead creature which I
offer them. To-day two hasten to the Mouse, who is soon perceived
overhead in the tuft of thyme.
