‘We have found that the electrostatic properties of the glue that coats spider webs causes them to reach out to grab all charged particles, from pollen and pollutants to flying insects. We also show that the glue spirals can distort the Earth’s electric field within a few millimetres of the web, which may enable insects to spot the webs with their antennae ‘e-sensors’.
