The Wonders of Instinct: Chapters in the Psychology of Insects
Fabre, Jean-Henri
Insects; Instinct
And these Epeirae, so terrible to insects, I am able to handle without
any fear. My skin does not suit them. If I persuaded them to bite me,
what would happen to me? Hardly anything. We have more cause to dread
the sting of a nettle than the dagger which is fatal to Dragon-flies.
The same virus acts differently upon this organism and that, is
formidable here and quite mild there. What kills the insect may easily
be harmless to us. Let us not, however, generalize too far. The
Narbonne Lycosa, that other enthusiastic insect-huntress, would make us
pay dearly if we attempted to take liberties with her.
It is not uninteresting to watch the Epeira at dinner. I light upon
one, the Banded Epeira, at the moment, about three o'clock in the
afternoon, when she has captured a Locust. Planted in the centre of the
web, on her resting-floor, she attacks the venison at the joint of a
haunch. There is no movement, not even of the mouth-parts, so far as I
am able to discover. The mouth lingers, close-applied, at the point
originally bitten. There are no intermittent mouthfuls, with the
mandibles moving backwards and forwards. It is a sort of continuous
kiss.
I visit my Epeira at intervals. The mouth does not change its place. I
visit her for the last time at nine o'clock in the evening. Matters
stand exactly as they did: after six hours' consumption, the mouth is
still sucking at the lower end of the right haunch. The fluid contents
of the victim are transferred to the ogress's belly, I know not how.
Next morning, the Spider is still at table. I take away her dish.
Naught remains of the Locust but his skin, hardly altered in shape, but
utterly drained and perforated in several places. The method,
therefore, was changed during the night. To extract the non-fluent
residue, the viscera and muscles, the stiff cuticle had to be tapped
here, there and elsewhere, after which the tattered husk, placed bodily
in the press of the mandibles, would have been chewed, re-chewed and
finally reduced to a pill, which the sated Spider throws up. This would
have been the end of the victim, had I not taken it away before the
time.
Whether she wound or kill, the Epeira bites her captive somewhere or
other, no matter where. This is an excellent method on her part,
because of the variety of the game that comes her way. I see her
accepting with equal readiness whatever chance may send her:
Butterflies and Dragon-flies, Flies and Wasps, small Dung-beetles and
Locusts. If I offer her a Mantis, a Bumble-bee, an Anoxia--the
equivalent of the common Cockchafer--and other dishes probably unknown
to her race, she accepts all and any, large and small, thin-skinned and
horny-skinned, that which goes afoot and that which takes winged
flight. She is omnivorous, she preys on everything, down to her own
kind, should the occasion offer.
