res are suppressed.

The rule is paralysis of all the segments, however many, in regular
order from front to back, including even the anal segment if this boast
of legs. By a fairly frequent exception the last two or three segments
are spared. Another exception, but a very rare one, of which I have
observed only a single instance, consists in the inversion of the
dagger-thrusts of the second act, the thrusts being delivered from back
to front. The caterpillar is then seized by its hinder extremity; and
the Ammophila, progressing towards the head, stings in reverse order,
passing from the succeeding to the preceding segment, including the
thorax already stabbed. This reversal of the usual tactics I am inclined
to attribute to negligence on the insect's part. Negligence or not,
the inverted method has the same final result as the direct method: the
paralysis of all the segments.

Lastly, the compression of the neck by the mandibulary pincers, the
munching of the weak spot between the base of the skull and the first
segment of the thorax, is sometimes practised and sometimes neglected.
If the caterpillar's jaws open and threaten, the Ammophila stills them
by biting the neck; if they are already growing quiescent, she refrains.
Without being indispensable, this operation is useful at the moment of
carting the prey. The caterpillar, too heavy to be carried on the wing,
is dragged, head first, between the Ammophila's legs. If the mandibles
are working, the least clumsiness may render them dangerous to the
carrier, who is exposed to their bite without any means of defence.

Moreover, once on the way, thickets of grass are traversed in which
the Grey Worm can seize a blade and offer a desperate resistance to
the traction. Nor is this all. The Ammophila does not as a rule trouble
about her burrow, or at least does not complete it, until she has
caught her caterpillar. During the mining-operations, the game is laid
somewhere high up, out of reach of the Ants, on some tuft of grass, or
the twigs of a shrub, whither the huntress, from time to time, stopping
her well-sinking, hastens to see if her quarry is still there. For her
this is a means of refreshing her memory of the spot where she has laid
it, often at some distance from the burrow, and of preventing attempts
at robbery. When the moment comes for removing the game from its
hiding-place, the difficulty would be insurmountable were the worm,
gripping the shrub with all the
