I put some more spider photos on my Patreon account — last time I neglected to mention that I also post some on Instagram, where they are free and you don’t even need an instagram account to see them.
I fed everyone big ol’ waxworms yesterday, and today they’ve been turned into big ol’ spider bellies. The ones I photographed are all new additions, spiders that were born here in my lab as tiny little spiderlings, and have now been successfully raised to pulchritudinous maturity.
I still occasionally post photos of my friendly neighborhood spider friends, but I’m avoiding putting them here. If you really, really like arachnids, you’ll have to join my Patreon to see my Breakfast at the Spider Ranch post. And if you really, really hate spiders, you don’t have to see them!
Hey, this is the same thing I tell everyone: spiders are mostly harmless, and they’re there whether you like them or not.
Spiders are not out to get you and actually prefer to avoid humans; we are much more dangerous to them than vice versa. Bites from spiders are extremely rare. Although there are a few medically important species like widow spiders and recluses, even their bites are uncommon and rarely cause serious issues.
If you truly can’t stand that spider in your house, apartment, garage, or wherever, instead of smashing it, try to capture it and release it outside. It’ll find somewhere else to go, and both parties will be happier with the outcome.
But if you can stomach it, it’s OK to have spiders in your home. In fact, it’s normal. And frankly, even if you don’t see them, they’ll still be there. So consider a live-and-let-live approach to the next spider you encounter.
The author of that article is also one of the authors of a paper I’m citing in something I’m working on now, in which he and colleagues did a thorough, room by room search for all arthropods in houses in a North Carolina region. One of their observations is that 100% of the homes had Theridiidae (common house spiders, like the Parasteatoda I’m studying) living in them. They’re kind of unavoidable. In my own much more limited survey (we only examined garages and sheds, and only arachnids, here in the harsher environment of Minnesota), we saw some similar results: almost all garages housed spiders. The one exception was eerily meticulous, everything stored away in tidy boxes, and no cobwebs or even dust. There are people who dust their garages! Unless you are that thorough, though, they’re there. And even if you are, they’ll sneak in — later that summer, we did find a few spiders in a shed on that same property. They looked terrified. Don’t worry, I didn’t rat out that they were there.
(Note: we were pretty strict about confidentiality, all locations are encoded in a file separate from the data on spider populations. You’d have to go through two sets of paper records matching addresses with spider counts to pin an identity on the houses with the most, or least, spiders.)
By the way, I have in mind proposing a workshop to Skepticon this year, an effort to counter arachnophobia. What I was thinking is a series of staged tables, where the beginning is something like 1) coloring pages of spider drawings, with explanations of anatomy; 2) a table of photos (maybe in trading card format?) of real spiders; 3) some small, caged spiders where we could observe feeding and courtship; and 4) a few harmless spiders, like Pholcidae, where people could actually let them clamber around their hands. Participants could ease in gradually and stop where ever they feel comfortable, and see people actually interact harmlessly with spiders.
What do you think? Would you actually participate in such a thing, if you had the opportunity? What number would you stop at?
I would not change my commute to avoid Main Street, I’d explicitly go down Main Street every day, and bring large animals with me. A diet of cars would be very bad for any spider, there’s not much nutrition there. What does it do? Bite through the outer shell, flood the interior with enzymes, and drink back the liquified upholstery? Yuck.
I put more spider photos on Patreon and Instagram. Today’s subjects are members of the tribe of Pholcus phalangioides who are dwelling in my basement. They seem to have undergone a population crash recently, though, probably because, while it’s warm enough in our house, they’re probably getting hungry at the lack of invertebrates to eat here in the depths of winter.
I said I’d stop flashing spider photos at you all, so really, it’s safe to come back here if you’re arachnophobic. I still occasionally indulge on the Patreon site, and I just added a few this morning (I’ll put them on Instagram shortly). My model was the lovely Danu, a Parasteatoda tepidariorum I caught at Skepticon in Missouri last August. My lighting setup was far short of ideal, though, so I’m going to have to work on that.
Yes, I still have those St Louis spiders in my lab, they’re doing fine, but in the absence of St Louis males, are not producing babies for me. I guess I’ll just have to go to Skepticon again this year and find some mates for them. Maybe if you go to Skepticon, I can draft you to help!
Usually, the science building I work in isn’t great for finding spiders — the custodians are good at their jobs. But sometimes, if you get down on your knees and poke around in the little crannies, you can find a few (I tell you, they’re everywhere, they’re just good at hiding). We explored my lab a bit today, and discovered a few things.
This may not be what some of you want to hear, but try getting down and looking under your furniture or in the dark gaps between your furniture and the wall. You may find you have friends.
It’s a busy day with all these job interview related things, but over my lunch hour I banged out 8 more spider cages, even with my gimpy left arm. I used a saw attachment on my Dremel (sorry, neighbors, if there was a lot of high-pitched screaming noises from my lab) to quickly hack up some bamboo strips and quarter-inch dowels, and then slapped them all together with hot glue. So easy.
I’m letting them cool now, and then I have to go through and clear out the threads of hardened glue scattered around — although the spiders probably won’t mind the strings — and let any fumes air out for a day, and then fill them up with more spiders.
And clean up. My lab is full of sawdust and little scraps of wood right now.
I scoop you up, put you in a cage, take photos of you, and give you flies to eat.
She’s very tiny. I’m going to have to fatten her up a lot.
