Hudson, W. H. (William Henry), 1841-1922

"The Naturalist in La Plata"

Nor is any very
intimate knowledge of spiders to be got from books, though numberless
lists of new species are constantly being printed; for they have not yet
had, like the social bees and ants, many loving and patient chroniclers
of their ways. The Hubens and Lubbocks have been many; the Moggridges
few. But even a very slight study of these most versatile and
accomplished of nature's children gives rise to some interesting
reflections. One fact that strikes the mind very forcibly is the
world-wide distribution of groups of species possessing highly developed
instincts. One is the zebra-striped Salticus, with its unique
strategy--that is to say, unique amongst spiders. It is said that the
Australian savage approaches a kangaroo in the open by getting up in
sight of its prey and standing perfectly motionless till he is regarded
as an inanimate object, and every time the animal's attention wanders
advancing a step or two until sufficiently near to hurl his spear. The
Salticus approaches a fly in the same manner, till near enough to make
its spring. Another is the Trapdoor spider. Another the Dolomedes, that
runs over the surface of the water in pursuit of its prey, and dives
down to escape from its enemies; and, strangest of all, the Argyroneta,
that has its luminous dwelling at the bottom of streams; and just as a
mason carries bricks and mortar to its building, so does this spider
carry down bubbles of air from the surface to enlarge its mysterious
house, in which it lays its eggs and rears its young.
