st host upon host of consumers, who are all
the more numerous and enterprising in proportion as the table is more
amply spread. The cherry of our orchards is excellent eating: a maggot
contends with us for its possession. In vain do we weigh suns and
planets: our supremacy, which fathoms the universe, cannot prevent a
wretched worm from levying its toll on the delicious fruit. We make
ourselves at home in a cabbage bed: the sons of the Pieris make
themselves at home there too. Preferring broccoli to wild radish, they
profit where we have profited; and we have no remedy against their
competition save caterpillar-raids and egg-crushing, a thankless,
tedious, and none too efficacious work.

Every creature has its claims on life. The Cabbage-caterpillar eagerly
puts forth his own, so much so that the cultivation of the precious
plant would be endangered if others concerned did not take part in its
defence. These others are the auxiliaries (The author employs this word
to denote the insects that are helpful, while describing as "ravagers"
the insects that are hurtful to the farmer's crops.--Translator's
Note.), our helpers from necessity and not from sympathy. The words
friend and foe, auxiliaries and ravagers are here the mere conventions
of a language not always adapted to render the exact truth. He is our
foe who eats or attacks our crops; our friend is he who feeds upon our
foes. Everything is reduced to a frenzied contest of appetites.

In the name of the might that is mine, of trickery, of highway robbery,
clear out of that, you, and make room for me: give me your seat at the
banquet! That is the inexorable law in the world of animals and more or
less, alas, in our own world as well!

Now, among our entomological auxiliaries, the smallest in size are the
best at their work. One of them is charged with watching over the
cabbages. She is so small, she works so discreetly that the gardener
does not know her, has not even heard of her. Were he to see her by
accident, flitting around the plant which she protects, he would take
no notice of her, would not suspect the service rendered. I propose to
set forth the tiny midget's deserts.

Scientists call her Microgaster glomeratus. What exactly was in the
mind of the author of the name Microgaster, which means little belly?
Did he intend to allude to the insignificance of the abdomen? Not so.
However slight the belly may be, the insect nevertheless possesses one,
