Spider webs more effective at ensnaring charged insects

[unable to retrieve full-text content]Flapping bees build up a charge of several hundred volts, enough to electrostatically draw pollen from a flower. But researchers have discovered a downside to being charged: it attracts spider silk and increases the chance that the bee or any insect will be snared by a web as it passes by. Perhaps, they say, the more flexible silk of an orb's spiral evolved to allow wind and electrostatic charge to improve capture success.
