Evaluating the behaviour of the spider species Enoplognatha ovata, a relative of the infamous Black Widow spider that despite being small is a formidable predator able to kill insects many times its size, the researchers found that when recordings of male leafhopper vibrational signals were played, the spiders picked up the signal and launched a food hunt.
