It is abundant in orchards and plantations round Buenos Ayres, where its
long and peculiarly soft, breezy note may be heard all summer. If the
ancient Athenians possessed so charming an insect as this, their great
regard for the grasshopper was not strange: I only wish that the
"Athenians of South America," as my fellow-townsmen sometimes call
themselves in moments of exaltation, had a feeling of the samo kind--the
regard which does _not_ impale its object on a pin--for the pretty
light-hearted songster of their groves and gardens.
When taken in the hand, it has the habit, common to most grasshoppers,
of pouring out an inky fluid from its mouth; only the discharge is
unusually copious in this species. It has another habit in defending
itself which is very curious. When captured it instantly curls its body
round, as a wasp does to sting. The suddenness of this action has more
than once caused me to drop an insect I had taken, actually thinking for
the moment that I had taken hold of a wasp. Whether birds would be
deceived and made to drop it or not is a question it would not be easy
to settle; but the instinct certainly looks like 'one of a series of
small adaptations, all tending to make the resemblance to a wasp more
complete and effective.
CHAPTER IX.
DRAGON-FLY STORMS.
One of the most curious things I have encountered in my observations on
animal life relates to a habit of the larger species of dragon-flies
inhabiting the Pampas and Patagonia.
