Gawain is a girl?

Today was the day I planned to start breeding my spiders. I have a group of definitely female black widows — they are easily recognizable, because they’re solid black spheres of voracious spiderhood.

Then I have another group set aside that I tentatively identified as male: they were smaller, had more slender abdomens, and just generally looked male. But their small size and slower growth meant they were still juveniles, and assigning sex was a bit more problematic. But they were growing fast, and I anticipated when I went into the lab today that at least some of them would be ready for mating.

I got a terrible surprise. Many of those males had died, unexpectedly. I suspect an epidemic of blue pedipalps, or that I’d waited too long and they died of unrequited love. I still have some vials with smaller presumptive males that I was afraid to offer to the females, because cannibalism, you know.

I had one large surviving male, I thought. Gawain. Gawain will come through for me and inseminate my females. Yes, Gawain would be the hero of the day! Except…

Gawain had become a girl.

Curse that campus-wide epidemic of infectious transgenderism!

She was actually almost certainly female all along, but had just matured enough that her sexual characteristics were inescapable. There go all my plans. She is quite pretty, though.

So now I have to be brave and maybe introduce some of the remaining diminutive males to the ladies, or I’m going to have to order some more black widows.

Sorry, the Christmas eve spider orgy has been cancelled.

The spiders will feast tonight!

When I become an evil overlord, that will be my catchphrase: “The spiders will feast tonight!”

I got to the bait shop this morning shortly after they got a bulk delivery, and just before they parceled them out into smaller batches, so I was able to buy a whole tub of 20 dozen (240) waxworms for $15.99. That’ll take care of feeding supplies for the next few weeks, right through Christmas, so mission accomplished.

Look at all that squirmy cold protein in thin casings! I was tempted to pop a few in my mouth, but that would be taking food from my babies, so I didn’t.

You need some more spider information

We just struggled to figure out how to put fitted sheets on a split-top bed, so I’m too tired to do it. Here are a few videos to do the job.

This first one is looking at spiders from an evolutionary perspective — it’s at a basic level, since the first thing it has to explain is that spiders aren’t insects.

This second one is more about spider cognition. It has a similar problem, since what it says isn’t really new. I took a grad-level physiology course from Michael Land in 1980 that focused almost entirely on jumping spiders, and we talked about similar things.

That course was the highlight of my first year of grad school. I guess it’s not surprising that I returned to spiders here in my dotage.
