<p><span class="upper">At</span> the end of July the Yellow-winged Wasp
tears the cocoon that has protected her till
then and flies out of her underground cradle. During
the whole of August she is often seen flitting
about the fields in search of honey. But this careless
life does not last long, for by the beginning of September
the Wasp must begin to dig her burrows and
search for game for her family. For her burrows
she usually chooses some sandy soil on the high
banks by the side of the road. One thing is necessary:
the site must receive plenty of sunshine.</p>
<p>Ten or twelve Yellow-winged Wasps usually
work together. They scrape the earth with their
fore-feet like mischievous puppies. At the same
time, each worker sings her glad song, which is a
shrill noise, constantly broken off and rising higher
<SPAN name="page-107" class="pagenum" href="#page-107" title="107"></SPAN>
or sinking lower in a regular rhythm. One would
think they were a troop of merry companions singing
to encourage each other in their work. Meanwhile,
the sand flies, falling in a fine dust on their
quivering wings; and the too-large gravel, removed
bit by bit, rolls far away from the work yard. If a
piece seems too heavy to be moved, the insect gets up
steam with a shrill note which reminds one of the
workman’s “Hoo!”</p>
<p>Soon the cave takes shape; the insect dives into
it bodily. We still hear underground her untiring
song, while every little while we catch a glimpse of
her hind-legs, pushing a torrent of sand backwards
to the mouth of the burrow. From time to time the
Wasp comes outside the entrance to dust herself in
the sun, and to rid herself of grains of sand. In
spite of these interruptions, she manages to dig the
gallery in two or three hours. Then she comes to
her threshold to chant her triumph and give the finishing
polish to her work by smoothing out some
unevenness and carrying away a speck or two of
earth.</p>
<p>There are two, three, or four cells in the Yellow-winged
Wasp’s burrow, in each of which lies an egg.
But the Wasp does not content herself with
one burrow: she digs about ten, all in the month of
September, and she has to get food for all of them.
She has not a moment to lose, when, in so short a
time, she has to dig her burrows, procure a dozen
Crickets or more for food for her families, and stop
the burrows up again. Besides, there are gray days
<SPAN name="page-108" class="pagenum" href="#page-108" title="108"></SPAN>
and rainy days during the month, when she cannot
work.</p>
<p>The Yellow-winged Wasp is not content with comparatively
defenseless Beetles and Caterpillars;
she hunts the powerful Cricket. Watch her
chasing one. The terrified Cricket takes to
flight, hopping as fast as he can; the Wasp pursues
him hot-foot, reaches him, rushes upon him. There
follows, in the dust, a confused struggle, wherein
each fighter is in turn victor and vanquished, on top
and underneath. The issue seems doubtful. But
at last the Wasp triumphs. In spite of his vigorous
kicks, in spite of the snaps of his pincer-like jaws,
the Cricket is laid low and stretched upon his back.</p>
<div class="figcenter"> <ANTIMG src="images/i_108.jpg" alt="she hunts the powerful Cricket" /></div>
<p><SPAN name="page-109" class="pagenum" href="#page-109" title="109"></SPAN>
The Wasp places herself upon him, belly to belly,
but in the opposite direction. She grasps one of the
threads at the tip of the Cricket’s abdomen with her
mouth and masters with her fore-legs the convulsive
efforts of his thick hinder-thighs. At the same time
her middle-legs hug the heaving sides of the
beaten insect, and her hind-legs force the joint
of the neck to open wide. The Wasp then
curves herself outward so as to offer the Cricket
no chance to bite her, and drives her poisoned sting
once into the victim’s neck, next into the joint of the
front two rings of the thorax, or part next the neck,
and lastly towards the abdomen. In less time than
it takes to tell, the murder is done; and the Wasp,
after making herself tidy again, gets ready to haul
home the victim.</p>
<p>You must acknowledge she knows how to fight,
better even than the Wasps who attack Beetles, or
those who capture Caterpillars. Those insects cannot
fly, they have no defensive weapons. What a
difference between them and the Cricket! The
Cricket is armed with dreadful jaws, capable of eating
the vitals out of the Wasp if they succeed in
seizing her; he has a pair of powerful legs, regular
clubs bristling with a double row of sharp spikes,
which can be used by the Cricket either to hop out
of his enemy’s reach, or to send her sprawling with
brutal kicks.</p>
<p>Notice, therefore, the precautions the Wasp takes
before setting her sting in motion. She turns the
Cricket upon his back so that he cannot use his hind-legs
<SPAN name="page-110" class="pagenum" href="#page-110" title="110"></SPAN>
to escape. She controls his spurred legs with
her fore-feet, so that he cannot kick her; and she
keeps his jaws at a distance with her own hind-legs.
She makes him motionless by grasping one of the
threads at the end of the abdomen. An athlete, an
expert wrestler, could not do better.</p>
<p>Consider, also, her science. She wishes to paralyze
the prey without killing it, so that it will remain
in a fit condition for food for her babies for many
weeks. If she should leave the Cricket any power
of motion, it would knock the eggs off; if she killed
it entirely, it would decay. How does she produce
this paralysis? She does just what a surgeon would
advise her to do; she strikes the nerve-centers of the
different parts of the Cricket’s body which are likely
to do harm, the three nervous centers that set the
legs in motion.</p>
<p>If we look at the Cricket a week, two weeks, or
even longer after the murder, we shall see the abdomen
moving slightly, a sign that he is still alive.</p>
<p>After the Wasp has paralyzed her Cricket, she
grips him with her feet, holding also one of his antennæ
in her mouth, and in this manner flies off with
him. She has to stop sometimes to take a minute’s
rest. Then she once more takes up her burden and,
with a great effort, carries him in one flight almost
to her home. The Wasp I am watching alights in
the middle of a Wasp village. She makes the rest
of her way on foot. She bestrides her victim and
advances, bearing her head proudly aloft and hauling
the Cricket, who trails between her legs, by the
<SPAN name="page-111" class="pagenum" href="#page-111" title="111"></SPAN>
antennæ held between her jaws. If the ground is
bare, she has an easy time; but sometimes she meets
with some spreading grass shoots, and then it is
curious to see her marches and countermarches, her
repeated attempts to get past, which she finally does
by some means or other, either by flight or by taking
another path.</p>
<p>At last she reaches home and places the Cricket
so that his antennæ exactly touch the mouth of the
burrow. The Wasp then leaves him and goes down
hastily to the bottom of the cave, perhaps to see
that everything is as it should be and no other Wasp
has made her nest there. A few seconds later she
reappears, showing her head out of doors and giving
a little cry of delight. The Cricket’s antennæ are
within her reach; she seizes them, and the game
is brought quickly down to the lair.</p>
<p>When the Yellow-winged Wasp has stacked up
three or four Crickets for each cell, she lays an egg
on one of them and closes the burrow. She does
this by sweeping the heaped-up sand outside the door
down the burrow. She mixes fair-sized bits of
gravel with the sand to make it stronger. If she
cannot find gravel of the right size within reach, she
goes and searches in the neighborhood, and seems
to choose the pieces as carefully as a mason would
choose the chief stones for his building. In a few
moments she has closed up the underground dwelling
so carefully that nothing remains to show where
it has been. Then she goes on, digs another burrow,
catches game for it, and walls it up. And so
<SPAN name="page-112" class="pagenum" href="#page-112" title="112"></SPAN>
on. When she is through laying all her eggs, she
goes back to the flowers, leading a careless, wandering
life until the first cold snap puts an end to her
existence, which has been so full of duties and excitements.</p>
