Another proof that it does not pour poison into the wound made by the ovipositor is, that the twig thus pierced and wounded does not swell, as in the case of plants wounded by Gall flies, which, perhaps, secrete an irritating poison, giving rise to tumors of various shapes.
I see them daily alighting on the envelopes and very busily exploring them, apprised of the contents by the gamy smell. Their incessant coming and going is a sign of intense cupidity; and yet none of them decides to lay on the bags. They do not even attempt to slide their ovipositor through the slits of the folds. The favourable season passes and not an egg is laid on the tempting wrappers.
In other characters, such as the want of compound eyes, the absence of wings, the absence of a complete ovipositor, and the occasional want of tracheæ, they stand at the base of the insect series.
These four pairs of appendages represent the four rings of the head, to which they are appended in the order stated above. A pair of legs is appended to each of the three rings of the thorax; while the first and second rings each usually carry a pair of wings. The abdomen contains the ovipositor; sometimes, as in the bees and wasps, forming a sting. Moreover, there are four pairs of legs.
And so they explore the cliff, going to and fro and up and down, with a flight that is now sudden, now smooth and slow. From time to time, I see the Anthrax quickly approach the wall and lower her abdomen as though to touch the earth with the end of her ovipositor. This proceeding takes no longer than the twinkling of an eye. When it is done, the insect alights elsewhere and rests.
In 1909, on Colonel Rondon's hardest trip, every man of the party had from one to five grubs deposited in him, the fly acting with great speed, and driving its ovipositor through clothing. The grubs cause torture; but a couple of cross cuts with a lancet permit the loathsome creatures to be squeezed out.
The insect is motionless, and hardly ten minutes elapse between the first cut of the ovipositor and the filling of the egg-chamber with eggs. The ovipositor is then withdrawn with methodical deliberation, in order that it may not be strained or bent.
The egg-chamber closes of its own accord as the woody fibres which have been displaced return to their position, and the Cigale climbs a little higher, moving upwards in a straight line, by about the length of its ovipositor. It then makes another puncture and a fresh chamber for another ten or twelve eggs. In this way it scales the twig from bottom to top.
Ovibos moschatus, horns of. Ovipositor of insects. Ovis cycloceros, mode of fighting of. Ovule of man.
This was attached to the bark by a touch, and from this starting-point the construction of the glistening house was continued, the apex of the ovipositor pouring out its endless puffy roll of aerated cement, which seemed to set as soon as laid.
