Canadian scientist thrills the web by live-tweeting spider sex

Like nurses, black cats, and pretty much every cultural group onEarth,spiders are often misrepresented by their depictions aroundHalloween.

Anything isspooky when it's the size of aminivanand hasan apparent thirst for human blood but real spiders can't grow much larger than28 centimetres,andthey certainlydon't want to attackyou.

And as an illuminatingseries of tweets from a University of Toronto PhD candidate show, spiders may actually have more in common with the Halloween revellers awkwardly trying to hook up after a partythan they do with any decorations outside.

Catherine Scottstudies courtship behaviour and sexual communication in black widow spiders, with a special interest inhow pheromones on spiders' silk are involved in attraction.

Clearly passionate about her work, Scott tweets about spiders constantly. Herfeed is a veritable wealth ofphotos, factsandstoriesabout the eight-legged animals, as well as a source of information for those who"might not yet be aware what fascinating creatures they are."

Friday was a day like many others for the PhD student as she conducted mating trials with a species of black widow (Latrodectus hesperus) in theAndrade lab at U of T's Scarboroughcampus.

She put three male spiders and three femalesinto a "mating arena," and then sat back to wait for theelaborate courtship displays to begin.

This, as her followers soon learned, can take quite some time.

"Since I was waiting around hoping to catch the spiders in the act, I thought I would tweet a bit," Scott told CBC News on Monday."I guess the weird and wonderful behaviour of black widows that originally got me hooked was also intriguing to folks following along."

It certainly was, judging by the amount of replies,retweets, favourites and follows that came her way that afternoon (and later, when Gizmodospotlighted her nowviral tweets.)

By the time Scott called it a night, about four hours after she started documenting the mating session and six after it started,spiderloversand casually interested observers alike were on the edge of their seats with anticipation.

"Maybe some nice lite jazz, soft lighting and a nice Chianti would help?" suggested one follower after Scott lamented that the spiders were "taking their time."

"Oh we've got super sexy red lighting up in here," she replied."And the romantic buzz of the laboratory air circulation."

And their excitement grew with every update Scott provided about the spiders' behaviour.

As Scott's tweets continued, it became clear that spider mating sessions are a lot more complicated andentertaining than most people know.

During lulls in the action, the scientist used her platform to further educate Twitter about everything from how black widows transfer spermand what their copulatory organs look liketo whether or not they actually participate in sexual cannibalism (rarely, she says.)

While Scott says she's "abit bewildered by the attention, to be honest," the fact that people were so interested in her tweets that afternoonmakes sense.

"I fell in love with spiders because of their fascinating courtship behaviour and sophisticated communication systems," she told CBC News. "Males perform elaborate courtship displays for the female, dancing and singing to get her attention and convince her to mate. If you've never seen theYouTubevideos of male peacock spiders dancing, I highly recommend checking them out!"

And dancing isn't the only thing males do to impress potential mates.

"Insome species male spiders give gifts to females," she said."But the gift is a dead insect wrapped in silk, and he brings it because if she's eating the gift she's less likely to eat him, and he'll be able to copulate longer than without a gift."

Sadly for those following the saga of Scott's spiders, none of her subjects were successful in their attempts to mate onFriday.

"As riveting as these last 5.5 hours have been, I have to go home and eat dinner," she tweeted around 5:30 p.m. ET. "I've set the cameras to continue recording in my absence. I'll check back tomorrow morning and look at the video.So sometime, in the near future, you can tune back in for some live-tweeting of the video watching. Advantage: fast-forward!!!!"

On Monday, Scott reported what she'd seen while watching the video and the news was anti-climactic for some.

"BTW I was able to go through the video from those mating trials this morning and as far as I can tell not a single mating occurred. ::::(" she tweeted.

All's well that ends well, though. The spiders will likelyget to try again in the future, and when they do, Scott's new followers will be more educated about what's going on than they were the first time.

"This month, for #Arachtober, my partner Sean and I have been tweeting about a different spider family every day to highlight their beauty and amazing diversity," she said. "Fridayafternoon's tweets weren't directly related to Arachtober... Mostly I was just bored. Tweeting my observations and seeing people's responses helped to remind me why I love black widows and their behaviour so much, though!"
