At other times the end is less quick and, above all, less repulsive. I
have kept a note of an Ephippiger who was dragging her satchel along
the ground and nibbling at it from time to time. The soil is uneven and
rugged, having been recently turned over with the blade of a knife. The
raspberry-like capsule picks up grains of sand and little clods of
earth, which increase the weight of the load considerably, though the
insect appears to pay no heed to it. Sometimes the carting becomes
laborious, because the load sticks to some bit of earth that refuses to
move. In spite of the efforts made to release the thing, it does not
become detached from the point where it hangs under the ovipositor,
thus proving that it possesses no small power of adhesion.
All through the evening, the Ephippiger roams about aimlessly, now on
the wirework, anon on the ground, wearing a preoccupied air. Oftener
still she stands without moving. The capsule withers a little, but does
not decrease notably in volume. There are no more of those mouthfuls
which the Ephippiger snatched at the beginning; and the little that has
already been removed affects only the surface.
Next day, things are as they were. There is nothing new, nor on the
morrow either, save that the capsule withers still more, though its two
red dots remain almost as bright as at first. Finally, after sticking
on for forty-eight hours, the whole thing comes off without the
insect’s intervention.
The capsule has yielded its contents. It is a dried-up wreck,
shrivelled beyond recognition, left lying in the gutter and doomed
sooner or later to become the booty of the Ants. Why is it thus
abandoned when, in other cases, I have seen the Ephippiger so greedy
for the morsel? Perhaps because the nuptial dish had become too gritty
with grains of sand, so unpleasant to the teeth.
Another Locustid, the Phaneroptera who carries a short yataghan bent
into a reaping-hook (P. falcata, Scop.), has made up to me in part for
my stud troubles. Repeatedly, but always under conditions which did not
allow of completing my observation, I have caught her carrying the
fertilizing-concern under the base of her sabre. It is a diaphanous,
oval phial, measuring three or four millimetres [61] and hanging from a
crystal thread, a neck almost as long as the distended part. The insect
does not touch it, but leaves the phial to dry up and shrivel where it
is. [62]
Let us be content with this. These five examples, furnished by such
different genera, Decticus, Analota, Grasshopper, Ephippiger and
Phaneroptera, prove that the Locustid, like the Scolopendra and the
Cephalopod, is a belated representative of the manners of antiquity, a
valuable specimen of the genetic eccentricities of olden times.
