"Nov. 18, 4:45 P.M.; released a fly in the cage. The spider pounced
upon it, seized it with fore and third pair of legs, threw out a band
of silk and enswathed it, tumbling it over and over with her hind feet
about thirteen times, hence enswathed it in thirteen wrappings of
silk. The fly was then disconnected from the web, the spider making
but little attempt to mend the gap. It was carried to the hub and
eaten. While the feast was going on, a honey-bee [with sting
extracted; we didn't want to run any risks with Argiope!] was
liberated in the cage. As soon as it touched the web, the spider was
upon it, throwing out a band of silk in a sheet a quarter of an inch
broad. ['Drawing out' would be more accurate, for the spinnerets
cannot spurt out silk; silk is drawn out and given its band character
by lightning-like movements of the comb-toothed hind feet.] With her
hind legs Argiope turned the bee over and over twenty-five or
twenty-six times, thus enswathing it with twenty-five or twenty-six
wrappings of the silken sheet.
"No sooner was the bee enswathed than a second bee was liberated in
the cage and caught in the web. This was treated by the spider like
bee No. 1.
"Nov. 20, 8:15 A.M.; Argiope perfectly still in center of hub,
feeding on bee No. 2. The only thing that reveals the feeding is a
slight moving of the bee's body as the juices are sucked up. Remains
of bee No. 1 dropped to the bottom of the cage.
"Fed all day, 8:15 A.M. to 5 P.M., on bee No. 2.
"At 2:30 P.M., a box-elder bug, which is very ill-smelling, was thrown
into the web. Argiope did nothing for three minutes, then went out on
the web to it and wrapped, making five complete turns; then went away.
Probably not hungry, as she has had two bees and a fly in three days.
"Nov. 21, 8:15 A.M.; box-elder bug finished during last night. Old web
replaced by a new one with twenty-nine radii, eleven complete spirals
and several partial spirals. The hub is formed of fine irregular
webbing about an inch and a half in diameter, without the viscid
droplets that cover the spirals. An open space of about a half-inch
intervenes between the hub and the beginning of the spirals.
"4:30 P.M.; liberated a fly in the cage. Argiope pounced upon it and
began to eat immediately, not taking time or trouble to enswath it.
"While the fly was being devoured, we liberated a strong-smelling
box-elder bug in the cage. It flew into the web. Argiope, by a quick
movement, turned on the hub toward the bug and stood in halting
position for eight seconds, then approached the bug slowly, hesitated
for a second or two, then wrapped it about with five wrappings, halted
again, and finally finished with five more wrappings. The bug was then
attached to the web where it had first touched, the spider passing
back to the center and resuming her meal.
