This is Scientific Americans' Sixty-Second Science, I'm Christopher Intagliata, got a minute?
Vampire 1 spiders, as the name suggests, like blood. And they feast on blood-filled mosquitoes to get it. But only female mosquitoes suck blood. So how do spiders hole in on the ladies?
To find out, researchers, well, took apart a bunch of mosquitoes. Then they mixed and matched body parts. They glued female heads onto male abdomens and male heads onto female bodies, some of which had blood-filled bellies 2. Then they let the spiders loose near these reassembled specimens 3, and watched to see which ones the spiders stalked.
As the researchers predicted, the spiders paid close attention to the abdomen, pouncing 4 on the Frankensquitos filled with blood. But the spiders also kept an eye ,or eight eyes, on the mosquitoes' heads. Males have lush, feathery *. The females aren't as so. So if the spiders couldn't see the belly 5 they went for female-headed mosquitoes, presumably for the better odds 6 of scoring blood. The researchs in the Journal of Experimental Biology.
Previous studies have shown that blood meals give vampire spiders a perfume that's irresistible 7 to the opposite sex. Now that's what I call bloodlust.
Thanks for the minute, for Scientific Americans' Sixty-Second Science, I'm Christopher Intagliata.
