find one another again if separated; but do not voluntarily separate;
realizing 〃the moral beauty of the double life〃 and 〃the touching concept
of the family; the sacred group par excellence。〃 The male buries himself
with his companion; remains faithful to her; comes to her assistance; and
〃stores up treasure for the future。 Never discouraged by the heavy labour
of climbing; leaving to the mother only the more moderate labour; keeping
the severest for himself; the heavy task of transport in a narrow tunnel;
very deep and almost vertical; he goes foraging; forgetful of himself;
heedless of the intoxicating delights of spring; though it would be so good
to see something of the country; to feast with his brothers; and to pester
the neighbours; but no! he collects the food which is to nourish his
children; and then; when all is ready for the new…comers; when their living
is assured; having spent himself without counting the cost; exhausted by
his efforts; and feeling himself failing; he leaves his home and goes away
to die; that he may not pollute the dwelling with a corpse。〃
The mother; on her side; allows nothing to divert her from her household;
and only returns to the surface when accompanied by her young; who disperse
at will。 Then; having nothing more to do; the devoted creature perishes in
turn。 (10/3。)
Compared with the Scarabaeus; which contents itself with idle wandering; or
even with the meritorious Sisyphus; does it not seem that the Minotaur
moves on an infinitely higher plane?
What nobler could be found among ourselves? What father ever better
comprehended his duties and obligations toward his family? What morality
could be more irreproachable; what fairer example could be meditated?
〃Is not life everywhere the same; in the body of the dung…beetle as in that
of man? If we examine it in the insect; do we not examine it in ourselves?〃
Whence does the Minotaur derive these particular graces? How has it risen
to so high a level on the wings of pure instinct? How could we explain the
rarity of so sublime an example; did we not know; to satiety; that 〃nature
everywhere is but an enigmatic poem; as who should say a veiled and misty
picture; shining with an infinite variety of deceptive lights in order to
evoke our conjectures〃? (10/4。)
Nevertheless; it is a fact that the majority have no other rule of conduct
than to follow the trend of their instincts; and to obey 〃their unbridled
desires。〃 No one better than Fabre has expounded the blind operation of
these little natural forces; the brutality of their manners; their
cannibalism; and what we might call their amorality; were it possible to
employ our human formulae outside our own human world。
With the gardener…beetles; if one is crippled; none of the same race halts
or lingers; none attempts to come to his aid。 Sometimes the passers…by
hasten to the invalid to devour him。〃
In the republic of the wasps 〃the grubs recognized as incurable are
pitilessly torn from their place and dragged out of the nest。 Woe to the
sick! they are helpless and at once expelled。〃
When the winter comes all the larvae are massacred; and the whole vespine
city ends in a horrible tragedy。
But life is a whole; and all conduct is good whose actions realize an
object and are adapted to an end。 If there is a 〃spirit〃 of the hive; the
insect also has its morality and the wasp's nest its 〃law;〃 and the conduct
of its inmates; horrible though it may seem to Fabre; is doubtless only a
submission to certain exigencies of that universal law which makes nature a
〃savage foster…mother who knows nothing of pity。〃
These cruelties particularly show us that one of the functions of the
insect in nature is to preside over the disappearance and also the ultimate
metamorphoses of the least 〃remnants of life。〃
Each has its providential hygienic function。
The Necrophori; 〃the first of the tiny scavengers of the fields;〃 bury
corpses in order to establish their progeny in them; in the space of a few
hours an enormous body; a mole; a water…rat; or an adder; will completely
disappear; buried under the earth。
The Onthophagi purify the soil; 〃dividing all filth into tiny crumbs;
ridding the earth of its defilements。〃
A very small beetle; the Trox; has the imprescriptible mission of purging
the earth of the rabbits' fur rejected by the fox。 (10/5。)
Here structure explains the function。
The intestine of the grub of the rose…beetle 〃is a veritable triturating
mill; which transforms vegetable matter into mould; in a month it will
digest a volume of matter equal to several thousand times the initial
volume of the grub。〃
The intestine of the Scarabaei is prolonged to a prodigious length in order
to 〃drain the excrement to the last atom in its manifold circuits。 The
sheep has finely divided the vegetable matter; the grub; that incomparable
triturator; reduces it to the finest possible consistency; not a morsel is
left in which the magnifying glass can reveal a fibre。〃
To fulfil its hygienic mission the insect arrives in due season; and
multiplies its legions; 〃there are twenty thousand eggs in the flanks of
the house fly; immediately they are hatched these twenty thousand maggots
set to work; so that Linnaeus has said that three flies would suffice to
devour the body of a horse or a lion。〃
Feeding only upon wheat; a single weevil; the Calendar beetle; produces ten
thousand eggs; whence issue as many larvae; each of them devouring its
grain。
In all species the number of births is at first exaggerated; for all; the
obscure; the nameless; the most destructive; our pests as well as our most
precious helpers; have their utility and their part to play in the general
scheme of life; a raison d'être in the eternal renewal of things; which is
without reference to the vexatious or beneficent quality of their behaviour
to us。
Each has its rank assigned; each has its task; to one the flower; to
another the roots; to a third the leaves; the vine has its caterpillars;
its beetles; its butterflies; the clover; its moths and mites。 (10/6。)
Man sees himself forced to submit to them; and spends himself in vain
efforts to carry on an often useless campaign。 Nothing seems to affect
them; neither drought; nor rain; nor even the severest cold; and the eggs
and larvae; organizations apparently delicate in the extreme; are often
more tenacious of life than the adults。 Fabre has proved this: let the
temperature suddenly fall twenty degrees: the eggs of Geotrupes and the
larvae of the cockchafer or the rose…beetle endure such vicissitudes of
temperature with impunity; contracted and stiffened into little masses of
ice; but not destroyed; they revive in spring no less than the eel fry; the
rotifers; or the tardigrades。 One can scarcely believe that life still
persists in a state of suspense only in these little frozen creatures;
whose organization is already so complicated。
Then; of a sudden; the ravagers disappear; more often than not none knows
how or why; deliverance is at hand。 What indeed would become of the world
were nothing to moderate such fecundity?
Again; each species has its trials which appear in time to moderate its
surplusage; and Fabre expounds for us; with a stern philosophy; the
terrible devices by which this repression is effected。
Each has its appointed enemy; which lives upon it or its offspring; and
which in turn becomes the prey of some smaller creature。 The gentle itself;
〃the king of the dead;〃 has its parasites。 While it swims in the
deliquescence of putrefying flesh a minute Chalcidian perforates its skin
with an imperceptible wound; and introduces its terrible eggs; whence in
the future will issue larvae which to…morrow will devour the devourers of
to…day。
None exists save to the detriment of others。 Everywhere; even in the
smallest; we find 〃an atrocious activity; a cunning brigandage;〃 a savage
extermination; which dominates a vast unconscious world of which the final
result is the restoration of equilibrium。 (10/7。) It is only on these
antagonisms; on the enemies of our enemies; that we can found any hope of
seeing this or that pest disappear。 A small Hymenopteron; almost invisible;
the Microgaster glomeratus; is entrusted with the destruction of the
cabbage caterpillar; the cochineal wages war to the death upon the green…
fly; the Ammophila is the predestined murderer of the harvest Noctuela;
whose misdeeds in a beetroot country often amount to a disaster。 The
Odynerus has for its instinctive mission to arrest the excessive
multiplication of a lucerne weevil; no less than twenty…four of whose grubs
are necessary to rear the offspring of the brigand; and nearly sixty
gadflies are sacrificed to the growth of a single Bembex。
Everywhere craft is organized to triumph over force。 Around each nest the
parasites lie in wait; 〃atrocious assassins of the child in the cradle;
watching at the doors for the favourable occasion to establish their family
at the expense of others。 The enemy penetrates the most inaccessible
fortress; each has its tactics of war; devised with a terrible art。 Of the
nest and the cocoon of the victim the intruder makes its own nest; its own
cocoon; and in the following year; instead of the master of the house; he
will emerge from underground as the usurping bandit; the devourer of the
inhabitant。〃
While the cicada is absorbed in laying her eggs an insignificant fly
labours to destroy them。 How express the calm audacity of this pigmy;
following closely after the colossus; step by step; several at once almost
under the talons of the giant; which could crush them merely by treading on
them? But the cicada respects them; or they would long ago have
disappeared。〃 (10/8。)
Fabre thus agrees with Pasteur; who in the world of the infinitely little
shows us the same antagonisms; the same vital competition; the same eternal
movement of flux and reflux; the same whirlpool of life; which is
extinguished only to reappear: tending always towards an equilibrium which
is incessantly destroyed。 And it is thanks to this balancing that the
integral of life remains everywhere and always almost identical with
itself。
CHAPTER 11。 HARMONIES AND DISCORDS。
Such indeed is the economy of nature that secret relations and astonishing
concordances exist throughout the whole vast weft of things。 There are no
loose ends; everything is consequent and ordered。 Hidden harmonies meet and
mingle。
Among the terebinth lice; 〃when the population is mature; the gall is ripe
also; so fully do the calendars of the shrub and the animal coincide〃; and
the mortal enemy of the Halictus; the sinister midge of the springtime; is
hatched at the very moment when the bee begins to wander in search of a
location for its burrows。
The fantastic history of the larvae o
