Arachne


BBC reports that:

Scientists have shed new light on how spiders can travel epic distances by dangling on strands of floating silk.
A team from Rothamsted Research, UK, has updated a mathematical model describing this remarkable arachnid phenomenon, known as "ballooning".

It claims the revision gives a more realistic explanation of what actually happens to spiders in flight.

The new model shows how turbulent air can propel the creatures much further - even hundreds of kilometres out to sea.

"By making some modifications we've solved something that's flummoxed scientists for 200 years," said Rothamsted's Dr Dave Bohan.

"The previous model could explain spiders going up to 200m; what it couldn't do was explain why, for example, Charles Darwin on his ship, The Beagle, more than 100km off the coast of South America, could watch ballooning spiders," he told BBC News.

One must make a model for that? In anne tyler's new novel, digging to america, a mother tries to get her daughter to get rid of her binkies by tying them to helium-filled balloons and letting them float away at a party. Similliar techniques used by spiders
