The Wonders of Instinct: Chapters in the Psychology of Insects
Fabre, Jean-Henri
Insects; Instinct
No, its place is not in the mass of provisions, for the caterpillars, I
repeat, are not sufficiently harmless. Their paralysis is incomplete,
as is proved by their contortions when I irritate them and shown, on
the other hand, by a very important fact. I have sometimes taken from
Eumenes Amedei's cell a few heads of game half transformed into
chrysalids. It is evident that the transformation was effected in the
cell itself and, therefore, after the operation which the Wasp had
performed upon them. Whereof does this operation consist? I cannot say
precisely, never having seen the huntress at work. The sting most
certainly has played its part; but where? And how often? This is what
we do not know. What we are able to declare is that the torpor is not
very deep, inasmuch as the patient sometimes retains enough vitality to
shed its skin and become a chrysalid. Everything thus tends to make us
ask by what stratagem the egg is shielded from danger.
This stratagem I longed to discover; I would not be put off by the
scarcity of nests, by the irksomeness of the searches, by the risk of
sunstroke, by the time taken up, by the vain breaking open of
unsuitable cells; I meant to see and I saw. Here is my method: with the
point of a knife and a pair of nippers, I make a side opening, a
window, beneath the dome of Eumenes Amedei and Eumenes pomiformis. I
work with the greatest care, so as not to injure the recluse. Formerly
I attacked the cupola from the top, now I attack it from the side. I
stop when the breach is large enough to allow me to see the state of
things within.
What is this state of things? I pause to give the reader time to
reflect and to think out for himself a means of safety that will
protect the egg and afterwards the grub in the perilous conditions
which I have set forth. Seek, think and contrive, such of you as have
inventive minds. Have you guessed it? Do you give it up? I may as well
tell you.
The egg is not laid upon the provisions; it is hung from the top of the
cupola by a thread which vies with that of a Spider's web for
slenderness. The dainty cylinder quivers and swings to and fro at the
least breath; it reminds me of the famous pendulum suspended from the
dome of the Pantheon to prove the rotation of the earth. The victuals
are heaped up underneath.
