Do you know? Spiders Use Electricity To Fly thousands of miles Without Wings ।

Scientists are now researching the use of spider venom in medicine and as non-polluting pesticides. Spider silk provides a combination of lightness, strength and elasticity that is superior to that of synthetic materials, and spider silk genes have been inserted into mammals and plants to see if these can be used as silk factories. As a result of their wide range of behaviors, spiders have become common symbols in art and mythology symbolizing various combinations of patience, cruelty and creative powers.
Do you spiders are one of the greatest creature of the earth. They’re an important part of the ecosystem and benefit humans by eating insects, including mosquitoes and agricultural pests. That said, many people are afraid of spiders, even the kinds that pose no risk to humans.
Spiders have no wings, but they can take to the air nonetheless. They’ll climb to an exposed point, raise their abdomens to the sky, extrude strands of silk, and float away. This behavior is called ballooning. It might carry spiders away from predators and competitors, or toward new lands with abundant resources. But whatever the reason for it, it’s clearly an effective means of travel. Spiders have been found two-and-a-half miles up in the air, and 1,000 miles out to sea.
It is reasonable to surmise that if e-fields are ecologically relevant, spiders should be able to detect and respond to an e-field by changing their behavior to engage in ballooning," the study stated.

Researchers placed Linyphiid spiders into a box that limited air movement but mirrored electric fields naturally present in atmospheric conditions. When the electric field was turned on, spiders showed a "significant increase in ballooning." The change in behavior demonstrated the spiders can detect when electricity is present.
