Wandering, as I am wont to do, through the pages of ScienceDaily.com, I thought… how about checking out the latest studies in arachnid sex!? Which brought me in pretty quick order to their recent article…
Yes, boys and girls, size matters… at least to male jumping spiders… at least when it comes to weapons.
OK, let me back-track a little bit.
The article begins, “If you’re a red-headed guy with eight bulging eyes and a unibrow, size does indeed matter for getting the girl. More specifically, the bigger a male jumping spider’s weapons appear to be, the more likely his rival will slink away without a fight, leaving the bigger guy a clear path to the waiting female.”
Duke University graduate student Cynthia Tedore wanted to know what visual signals matter most to magnolia green jumping spiders, which have an impressive array of eyes, including two giant green ones that face forward. The benefit of these huge green eyes is key to Tedore’s studies and findings.
Vision is clearly important to these quarter-inch animals, which can be “very predaceous and aggressive,” when love is in the air.
In Tedore’s lab in the basement of Duke’s biological sciences building, wire shelves are covered with row after row of Lucite boxes, each holding an individual chartreuse jumping spider.
How does she test the ‘more is more’ theory? Using female spider silk to put them in a competitive mood, Tedore pits the male spiders against one another in a one-on-one cage match! Rage in a Cage. Hell in a Cell. All in the name of science! 
So what did Tedore discover? Over the course of 68 of these cage matches, the male with the bigger chelicerae (heavy, bristling fangs hanging in front of their mouth parts), usually scared the other guy off without a fight.
“The males wave their forelegs at each other for a period, and then the smaller male runs off,” Tedore said. “That’s why we think they’re using vision to size each other up. Most of the time, the smaller one will run away before it comes to blows.”
Seven of the matches were scored as ties. Seventeen of the contests turned into shoving matches, with the spiders butting chelicerae against each other. Occasionally one would flip an opponent on his back, then chase and pounce on him. Tedore had to break up a couple of contests before time expired so that nobody got hurt. 
Tedore said her work provides another glimpse into how these creatures, which have tiny brains and never met their parents, manage to make decisions and navigate their world. “I don’t really think of them as conscious, but they’re following rules of some kind. I think of them more as robots.”
In her next series of experiments, Tedore is pitting males against video images of other males that have artificially exaggerated chelicerae and altered colors. 
I… can’t… wait!!!
 I’m liking this girl more and more!
 Seriously, now… how can you NOT like this girl!!??
 Cynthia… you are my idea of a wonderful woman!
