These proceedings are marked by extreme prudence. The assailant has to
handle his victim gingerly, without provoking contractions which would
make the Snail let go his support and, at the very least, precipitate
him from the tall stalk whereon he is blissfully slumbering. Now any
game falling to the ground would seem to be so much sheer loss, for the
Glow-worm has no great zeal for hunting-expeditions: he profits by the
discoveries which good luck sends him, without undertaking assiduous
searches. It is essential, therefore, that the equilibrium of a prize
perched on the top of a stalk and only just held in position by a touch
of glue should be disturbed as little as possible during the onslaught;
it is necessary that the assailant should go to work with infinite
circumspection and without producing pain, lest any muscular reaction
should provoke a fall and endanger the prize. As we see, sudden and
profound anaesthesia is an excellent means of enabling the Lampyris to
attain his object, which is to consume his prey in perfect quiet.

What is his manner of consuming it? Does he really eat, that is to say,
does he divide his food piecemeal, does he carve it into minute
particles, which are afterwards ground by a chewing-apparatus? I think
not. I never see a trace of solid nourishment on my captives' mouths.
The Glow-worm does not eat in the strict sense of the word: he drinks
his fill; he feeds on a thin gruel into which he transforms his prey by
a method recalling that of the maggot. Like the flesh-eating grub of
the Fly, he too is able to digest before consuming; he liquefies his
prey before feeding on it.

This is how things happen: a Snail has been rendered insensible by the
Glow-worm. The operator is nearly always alone, even when the prize is
a large one, like the common Snail, Helix aspersa. Soon a number of
guests hasten up--two, three, or more--and, without any quarrel with
the real proprietor, all alike fall to. Let us leave them to themselves
for a couple of days and then turn the shell, with the opening
downwards. The contents flow out as easily as would soup from an
overturned saucepan. When the sated diners retire from this gruel, only
insignificant leavings remain.

The matter is obvious. By repeated tiny bites, similar to the tweaks
which we saw distributed at the outset, the flesh of the Mollusc is
converted into a gruel on which the various banqueters nourish
themselves without distinction, each w
