This process is continued for twenty minutes or so. Then the capsule,
now drained, is torn off in a single piece, all but the jelly plug at
the end. The huge, sticky mass is not let go for a moment, but is
munched, ground and kneaded by the insect’s mandibles and at last
gulped down whole.
At first I looked upon the horrible banquet as no more than an
individual aberration, an accident: the Decticus’ behaviour was so
extraordinary; no other instance of it was known to me. But I have had
to yield to the evidence of the facts. Four times in succession I
surprised my captives dragging their wallet and four times I saw them
soon tear it, work at it solemnly with their mandibles for hours on end
and finally gulp it down. It is therefore the rule: when its contents
have reached their destination, the fertilizing capsule, possibly a
powerful stimulant, an unparalleled dainty, is chewed, enjoyed and
swallowed.
If this, as we are entitled to believe, is a relic of ancient manners,
we must admit that the insect of old had singular customs. Réaumur
tells us of the startling operations of the Dragon-flies when pairing.
This again is a nuptial eccentricity of primeval times.
When the Decticus has finished her strange feast, the end of the
apparatus still remains in its place, the end whose most visible part
consists of two crystalline nipples the size of pepper-corns. To rid
itself of this plug, the insect assumes a curious attitude. The
ovipositor is driven half-way into the earth, perpendicularly. That
will be the prop. The long hind-legs straighten out, raise the creature
as high as possible and form a tripod with the sabre.
Then the insect again curves itself into a complete circle and, with
its mandibles, crumbles to atoms the end of the apparatus, consisting
of a plug of clearest jelly. All these remnants are scrupulously
swallowed. Not a scrap must be lost. Lastly, the ovipositor is washed,
wiped, smoothed with the tips of the palpi. Everything is put in order
again; nothing remains of the cumbrous load. The normal pose is resumed
and the Decticus goes back to pilfering the ears of millet.
To return to the male. Limp and exhausted, as though shattered by his
exploit, he remains where he is, all shrivelled and shrunk. He is so
motionless that I believe him dead. Not a bit of it! The gallant fellow
recovers his spirits, picks himself up, polishes himself and goes off.
A quarter of an hour later, when he has taken a few mouthfuls, behold
him stridulating once more. The tune is certainly lacking in spirit. It
is far from being as brilliant or prolonged as it was before the
wedding; but, after all, the poor old crock is doing his best.
