Researchers Experiment over Spiders to Learn How they Trap Insects
Experts have finally found links to answer how spiders attract insects and trap them in their silky web. They explain the spider web has a negative electrical charge, which becomes effective upon the positively charged insects and cause the fatal attraction.
Above are the conclusions drawn through an experiment that was recently conducted by experts in a lab environment isolated from electrical fields. The experiment was conducted by UC Berkeley post-doctoral fellow Mr. Victor Manuel Ortega-Jimenez and his colleague Mr. Robert Dudley.
The former expert is into researching with hummingbirds and moths whereas the latter provided the research with a variety of newly-dead insects like bumblebees and fruit flies.
Experts explain in their findings that the insects when fly they build up an electrical charge in their body, which is attracted to the spider web that has either a positive or neutral charge.
"The spider web is really interesting because it's so thin and flexible. The web is attracted to the insect, so that can increase the spider's capture rate", said Ortega-Jimenez. The idea of running the above experiment was of Mr. Ortega.
While playing with his daughter, he noticed that his four-year-old daughter's magic wand toy actually attracted the spider web and bent it towards her wand. He wanted to use the same theory to learn about the oppositely charged objects.
