CHAPTER VII

THE MANTIS: HER LOVE-MAKING

The little that we have seen of the Mantis’ habits hardly tallies with

what we might have expected from her popular name. To judge by the term

Prègo-Diéu, we should look to see a placid insect, deep in pious

contemplation; and we find ourselves in the presence of a cannibal, of

a ferocious spectre munching the brain of a panic-stricken victim. Nor

is even this the most tragic part. The Mantis has in store for us, in

her relations with her own kith and kin, manners even more atrocious

than those prevailing among the Spiders, who have an evil reputation in

this respect.

To reduce the number of cages on my big table and give myself a little

more space while still retaining a fair-sized menagerie, I instal

several females, sometimes as many as a dozen, under one cover. So far

as accommodation is concerned, no fault can be found with the common

lodging. There is room and to spare for the evolutions of my captives,

who naturally do not want to move about much with their unwieldy

bellies. Hanging to the trelliswork of the dome, motionless they digest

their food or else await an unwary passer-by. Even so do they act when

at liberty in the thickets.

Cohabitation has its dangers. I know that even Donkeys, those

peace-loving animals, quarrel when hay is scarce in the manger. My

boarders, who are less complaisant, might well, in a moment of dearth,

become sour-tempered and fight among themselves. I guard against this

by keeping the cages well supplied with Locusts, renewed twice a day.

Should civil war break out, famine cannot be pleaded as the excuse.

At first, things go pretty well. The community lives in peace, each

Mantis grabbing and eating whatever comes near her, without seeking

strife with her neighbours. But this harmonious period does not last

long. The bellies swell, the eggs are ripening in the ovaries, marriage

and laying-time are at hand. Then a sort of jealous fury bursts out,

though there is an entire absence of males who might be held

responsible for feminine rivalry. The working of the ovaries seems to

pervert the flock, inspiring its members with a mania for devouring one

another. There are threats, personal encounters, cannibal feasts. Once

more the spectral pose appears, the hissing of the wings, the fearsome

gesture of the grapnels outstretched and uplifted in the air. No

hostile demonstration in front of a Grey Locust or White-faced Decticus

could be more menacing.

For no reason that I can gather, two neighbours suddenly assume their

attitude of war. They turn their heads to right and left, provoking

each other, exchanging insulting glances. The “Puff! Puff!” of the

wings rubbed by the abdomen sounds the charge. When the duel is to be

limited to the first scratch received, without more serious

consequences, the lethal fore-arms, which are usually kept folded, open

like the leaves of a book and fall back sideways, encircling the long

bust. It is a superb pose, but less terrible than that adopted in a

fight to the death.

Then one of the grapnels, with a sudden spring, shoots out to its full

length and strikes the rival; it is no less abruptly withdrawn and

resumes the defensive. The adversary hits back. The fencing is rather

like that of two Cats boxing each other’s ears. At the first blood

drawn from her flabby paunch, or even before receiving the least wound,

one of the duellists confesses herself beaten and retires. The other

furls her battle-standard and goes off elsewhither to meditate the

capture of a Locust, keeping apparently calm, but ever ready to repeat

the quarrel.

Very often, events take a more tragic turn. At such times, the full

posture of the duels to the death is assumed. The murderous fore-arms

are unfolded and raised in the air. Woe to the vanquished! The other

seizes her in her vice and then and there proceeds to eat her,

beginning at the neck, of course. The loathsome feast takes place as

calmly as though it were a matter of crunching up a Grasshopper. The

diner enjoys her sister as she would a lawful dish; and those around do

not protest, being quite willing to do as much on the first occasion.

Oh, what savagery! Why, even Wolves are said not to eat one another.

The Mantis has no such scruples; she banquets off her fellows when

there is plenty of her favourite game, the Locust, around her. She

practises the equivalent of cannibalism, that hideous peculiarity of

man.

These aberrations, these child-bed cravings can reach an even more

revolting stage. Let us watch the pairing and, to avoid the disorder of

a crowd, let us isolate the couples under different covers. Each pair

shall have its own home, where none will come to disturb the wedding.

And let us not forget the provisions, with which we will keep them well

supplied, so that there may be no excuse of hunger.

It is near the end of August. The male, that slender swain, thinks the

moment propitious. He makes eyes at his strapping companion; he turns

his head in her direction; he bends his neck and throws out his chest.

His little pointed face wears an almost impassioned expression.

Motionless, in this posture, for a long time he contemplates the object

of his desire. She does not stir, is as though indifferent. The lover,

however, has caught a sign of acquiescence, a sign of which I do not

know the secret. He goes nearer; suddenly he spreads his wings, which

quiver with a convulsive tremor. That is his declaration. He rushes,

small as he is, upon the back of his corpulent companion, clings on as

best he can, steadies his hold. As a rule, the preliminaries last a

long time. At last, coupling takes place and is also long drawn out,

lasting sometimes for five or six hours.

Nothing worthy of attention happens between the two motionless

partners. They end by separating, but only to unite again in a more

intimate fashion. If the poor fellow is loved by his lady as the

vivifier of her ovaries, he is also loved as a piece of

highly-flavoured game. And, that same day, or at latest on the morrow,

he is seized by his spouse, who first gnaws his neck, in accordance

with precedent, and then eats him deliberately, by little mouthfuls,

leaving only the wings. Here we have no longer a case of jealousy in

the harem, but simply a depraved appetite.

I was curious to know what sort of reception a second male might expect

from a recently fertilized female. The result of my enquiry was

shocking. The Mantis, in many cases, is never sated with conjugal

raptures and banquets. After a rest that varies in length, whether the

eggs be laid or not, a second male is accepted and then devoured like

the first. A third succeeds him, performs his function in life, is

eaten and disappears. A fourth undergoes a like fate. In the course of

two weeks I thus see one and the same Mantis use up seven males. She

takes them all to her bosom and makes them all pay for the nuptial

ecstasy with their lives.

Orgies such as this are frequent, in varying degrees, though there are

exceptions. On very hot days, highly charged with electricity, they are

almost the general rule. At such times the Mantes are in a very

irritable mood. In the cages containing a large colony, the females

devour one another more than ever; in the cages containing separate

pairs, the males, after coupling, are more than ever treated as an

ordinary prey.

I should like to be able to say, in mitigation of these conjugal

atrocities, that the Mantis does not behave like this in a state of

liberty; that the male, after doing his duty, has time to get out of

the way, to make off, to escape from his terrible mistress, for in my

cages he is given a respite, lasting sometimes until next day. What

really occurs in the thickets I do not know, chance, a poor resource,

having never instructed me concerning the love-affairs of the Mantis

when at large. I can only go by what happens in the cages, where the

captives, enjoying plenty of sunshine and food and spacious quarters,

do not seem to suffer from homesickness in any way. What they do here

they must also do under normal conditions.

Well, what happens there utterly refutes the idea that the males are

given time to escape. I find, by themselves, a horrible couple engaged

as follows. The male, absorbed in the performance of his vital

functions, holds the female in a tight embrace. But the wretch has no

head; he has no neck; he has hardly a body. The other, with her muzzle

turned over her shoulder continues very placidly to gnaw what remains

of the gentle swain. And, all the time, that masculine stump, holding

on firmly, goes on with the business!

Love is stronger than death, men say. Taken literally, the aphorism has

never received a more brilliant confirmation. A headless creature, an

insect amputated down to the middle of the chest, a very corpse

persists in endeavouring to give life. It will not let go until the

abdomen, the seat of the procreative organs, is attacked.

Eating the lover after consummation of marriage, making a meal of the

exhausted dwarf, henceforth good for nothing, can be understood, to

some extent, in the insect world, which has no great scruples in

matters of sentiment; but gobbling him up during the act goes beyond

the wildest dreams of the most horrible imagination. I have seen it

done with my own eyes and have not yet recovered from my astonishment.

Was this one able to escape and get out of the way, caught as he was in

the midst of his duty? Certainly not. Hence we must infer that the

loves of the Mantis are tragic, quite as much as the Spider’s and

perhaps even more so. I admit that the restricted space inside the

cages favours the slaughter of the males; but the cause of these

massacres lies elsewhere.

Perhaps it is a relic of the palæozoic ages, when, in the carboniferous

period, the insect came into being as the result of monstrous amours.

The Orthoptera, to whom the Mantes belong, are the first-born of the

entomological world. Rough-hewn, incomplete in their transformation,

they roamed among the arborescent ferns and were already flourishing

when none of the insects with delicate metamorphoses, Butterflies,

Moths, Beetles, Flies and Bees, as yet existed. Manners were not gentle

in those days of passion eager to destroy in order to produce; and the

Mantes, a faint memory of the ghosts of old, might well continue the

amorous methods of a bygone age.

The habit of eating the males is customary among other members of the

Mantis family. I am indeed prepared to admit that it is general. The

little Grey Mantis, who looks so sweet and so peaceable in my cages,

never seeking a quarrel with her neighbours however crowded they may

be, bites into her male and feeds on him as fiercely as the Praying

Mantis herself. I wear myself out, scouring the country to procure the

indispensable complement to my gynæceum. No sooner is my

powerfully-winged and nimble prize introduced than, most often, he is

clawed and eaten up by one of those who no longer need his aid. Once

the ovaries are satisfied, the Mantes of both species abhor the male,

or rather look upon him as nothing better than a choice piece of

venison.
